- 008 - Energy Flow in Ecosystems
In this video Paul Andersen explains how energy flows in ecosystems. Energy enters via producers through photosynthesis or chemosynthesis. Producers and consumers release the energy from food through cellular respiration. An explanation of gross primary productivity and net primary productivity are included. Energy and biomass in ecological pyramids show energy efficiency.

for ayone at k12 who needs the times for the questions here u go. 0:20 , 0:51
1:03 2:19 3:13 3:36 4:53 5:23 5:43 6:31 . hope this helps :)
You are the GOAT!🐐
So where are these questions located?
Thanks
@@cotystill9927 yeah i cant hear him asking any questions
que grande
I cannot believe high school students study this! I never did. Nothing even close to it in HS. Everything was general.
Now as an adult I’m like WT?! and my teens are like, yeah duh - we learned this. You’re generation is going to do so much for our environment. This is so important in understanding our anthropological affects on the environment. You will be the generation that heals our planet! 💕🤗
Very helpful! I want to be able explain this as clearly as you did one day. I appreciate your videos! Thank you so much.
Thank you! I appreciate your comment as a senior striving to be an environmentalist :)
Hi, do u like black people!@@manyasuhag6577
You really are such a good teacher. Clear, pleasant and good at using models and examples that are easy to understand. Great job!
wow!!! i learned sooooooooooooooooooooooooo much in this video it was sooooooooooooooooo helpful thank you sooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo much i will share this to all my friends and you sound so excited during this vid
A real quick thing I want to add, the energy pyramid. There is a role of the 2nd law of thermodynamics, "energy does not diminish, but the ability to use it does." Something like that, that's why you see only 10% of the energy being passed down, due to respiration taking most of it and keep in mind of that law.
In my office now
devilwolverine K
coz the rest of the energy is lost in the day to day function (like making heat)
Turn on subtitles and slow down the video to 0.75 or 0.5 if it is too fast for you.
Good video. Watched it in class.
Nightcat bruh what? I speed up the video cuz he talks so slow lol
@@abdussaboormuhammad906 yea bro
I have a Biology test next Tuesday, and you summed up all the 9th grade 3rd season material that is included in this test, I understand everything now :D thx
your videos have been crucial while learning during quarantine!!!
Very well explained and very helpfull too!! Good Video
Thanks man. For the people who are complaining its too fast, just turn on subtitles and turn the video speed down to like 0.75 or 0.5. Jeez like srsly guys. Stop being so bloodsucking.
Yeoo I have a science test on this tmrw so this helped😂
great high quality video, really helped me, thanks
Wow! The Video Help me a lot sir . Thanks for making an Perfect video for me cause I have an Lesson relate to this in my Biology book . Thanks for this Video .
Thanks! Always a great help to clear some concepts.
ratio then
So incredibly helpful thank you
excellent video. masterfully made.
Nice work, I understood everything
Amazing video! Thank you so much!
Thank you for these videos! Great learning resources for college-level intro environmental science students.
Very helpful we here all appreciate this
Love silver springs! Love your videos!
wow .. thank u that was pretty helpful
thnk youuuu. it's really helpful!
Thank you really much for everything you teach! You are so good 😊
Hi
How are you
THANK YOU MR ANDERSON
Very helpful!
For all those people complaining about how he was going too fast, there is a pause button guys! I paused the video a few times myself
it's better than hank green's gibberish on crash course
yeah get some friends
or they could just change the speed into 0.75 :D
03Indie 👟👟
You can’t really pause it when you’re in class watching it.
Bro thank you for this video, really appreciate it!
Bro you a puss
Thank you!! So clear! Now I understand everything ;)
Oh wow you hit 100,000 views :) congrats! So helpful :D
That video is very interesting and i have learned too many things from these
Love the way he teach🤗
thank you so much
Thank you so much! Your video's are very helpfull and clear!
Lmaooo shut up
@Gavin Langman hush bozo 😹😹😹👎🏼👎🏼👎🏼🤦🤦🤦
Thanks
Best voice ever
Illuminating. Thx.
I love you Mr. Anderson.
Paul, can you imagine a way we could industrialize these processes; chemosythesis and/or photosynthesis?
If we could take our own waste carbon dioxide and use it to produce sugars, would that be a cost effective way to save on production time such that it might entice corporations to get into the business? It would free up a lot of land that we could use for other things, like sanctuaries, preserves, mining or just to reduce the cost of living so that people could distribute themselves more evenly around the globe and not be so isolated to ports where our other waste products may harm things like aquatic biomes such as coral reefs.
I've been thinking about this for a long time, but in terms of production in space and on other worlds, but the benefits would really help here on Earth, especially with the big panic over CO2 production over the last 20 years or so.
I was thinking on places like Mars and Venus, after reading The Case for Mars by Robert Zubrin. He discussed the Sabatier reaction, CO2 + 4 H2 → CH4 + 2 H2O + energy, but if we could convert that CO2 into C6H12O6, we'd have fuel for life forms as well. On Venus maybe if we could use the SO2 in the atmosphere the way H2S is used in chemosynthesis, we could get the ball rolling for life there.
Lots to think about.
great video , sir :))
if u look at him from your peripheral vision all of a sudden it feels like his head is floating in space
My life is now complete
Very helpful
Chad faced John green
he looks like luke skywalker to me
very helpful thanks
Very helpful Thank you ma teacher ☺😊
Good video
Thq soo much sir ❤️ these a help to do my assignment......
Thank u sir it really helped me ❤ 😊
this helps sooooooooo much
College senior level ecology is harder than i thought. i was hoping it would be like animal planet lol
SOOOOO INFORMITIVE !!!
god bless this man
best explanation
Thanks for this video super
Hi! Just curious, but can higher trophic levels get energy from other trophic levels that aren't right below it? I'm almost certain they can but I just want some confirmation
I love ur teaching style ...I m glad I found Ur videos...thanks Mann..
Thanks
Literally helps me a lot sir thankyou
From INDIA
Nice Vid
Thank you, so much. Can you tell me about what food we can eat that balance our human Ecosytems
I would suggest food yk not grass but like lettuce maybe.
That was helpful. When you say that there is a common misconception that plants respire, do you mean it is a misconception that plants respire with byproducts of CO2 and H2O? Because later on in the video, you said plants use about 60% of energy through respiration.
around 5:40
if we consume more primary producers like plants, does it mean that we can gain more energy?
Very helpful
got A on my test
thank you
Anyone else is here because of "Biology Class"
Yup
Ily so much, you are the reason im not dropping biology
school? anyone
an egg yeah he's a teacher at my school so we have to watch these videos ALL THE TIME...
cool! you have an epic teacher...BTW which school and which country?
@@justbored6262 youre so lucky hes so good!!!
Yesss me
Nooooo
where can I find information about Energy Flow in Polar regions, thanks.
i love you mr anderson
Thanks,Gracia's....
If the pyramid of biomass in aquatic ecosystem is inverted then how can higher tropic level organisms get the energy if only 10% is sent in higher tropic level. PLEASE HELP!
Yo tysm for that 100%
thanks
do u know some good topics to cover in biology and chemistry?
super
This was very helpful although I didn't pay much attention sorry teacher of you see this :)
I never pay attention to videos
Thank you soo much!!!!
My teacher made me watch this in class
"I hope that is helpful". Definitely, it is helpful!
Can't the secondary consumers consume the plants and the primary consumers,
making them primarily omnivores?
If so, then 5:27 is a little simplified.
i just watched this in class!!! im still in class!!!
hahahaahahahaahahhahaahhahahahha lol
imagine if he got a gold play button for teaching
Just a simple question. Why do some animals, such as birds and alligators, help each other by the bird cleaning the alligators teeth and the alligator not eating the bird? I never understood that.
It's called a symbiotic relationship (mutually beneficial). Both benefit each other's survival.
thanks.
2:30 This one took me a good minute to sort out for myself even though it took you only 7 seconds to say it. "Misconception"? I think you mean "Something not often known." You use that word but immediately go on to explain the right idea, which is exclusively the opposite of a misconception. You might understand my confusion? As a listener, when I hear a setup like "One misconception is," I expect the misconception to be stated, and a correction to be stated. It's subconscious.
Maybe I'm nitpicking, but this has the potential to be a problem.
The change in subject came as a surprise. I felt like I was left with a cliffhanger, so my attention was adrift as the lecture continued.
Many listeners may smooth over their critical thinking when they hear something that dissonant. I mean that they may just make an arbitrary decision on the fly as to what you meant without stopping to think so they won't miss anything. I wonder if a significant fraction of listeners will remember plants as NOT doing cell respiration since that's what anticipation would first determine.
Thanks for following up with the clarifying sentence at 2:33 or I would have been misinformed rather than momentarily confused.
Saohesc thought was the only one to notice
I was so annoyed when I realized how perfect those words were for causing confusion. Anything else might have been incorrect, but easier to figure out. I'm glad I went on to explain myself plainly despite doubting my motivations as purely emotional.
Reinventing the Glial nice thesaurus
Can some one answers my question please if the primary producers aka plants have the most energy how come they have less calories than tertiary consumers? My theory is that these animals are constantly eating therefore they create their fat reserves piling up energy aka calories
vamos por la 30 mr anderson
So would it be more efficient (energy wise) to eat a cow then rather eating a lion?
Have an Ecology exam tomorrow and I'm watching this , 2021
👏
Best
Wait i have a question. So we have the 10 percent law by leinderman...so as there is a 10% loss of energy along the trophic level...so vegeterians more energy efficient than non vegeterians ? So is it better to be a vegeterian ?
@Eileen Antrobus not true
Could someone write down the questions he asked cause i didn't get any of them
do it yourself
Can anyone tell which is the most efficient pyramid in terms of energy at 7:01
The most efficient in terms of energy transfer would be the Eniwetok coral reef.
1:35 for complete chart
I live to study things about the earth and soil..soil has got soul...
fr saving me in bio rn
when i bored from my teacher i came to youtube
Stfu
So can we conclude that if the human population becomes vegetarian then as secondary consumers (rather than tertiary) there will be more energy to sustain a growing world populations?
+Liz Taylor no, because without our predation, the other secondary consumers would run wild and eat the plants
That is indeed a good assumption. I would add that vegetarian should be vegan in that case.
@xiACX123; we breed the animals we eat so with less consumption of animals, less breeding will occur. No animals will run wild and eat your broccoli ;)
I'd say the major problem isn't having enough energy but enough room. We're running out of space for agriculture due to growing human populations. Regardless of whether we're eating crops or meat, if we don't have room for agriculture... we're fucked :(
Well, all great points but the animals wouldn't run wild and overtake consumers because our ecosystem runs on negative-feedback inhibition which means there are natural control systems on population control. Additionally, we would not run out of room for agriculture because according to a 2016 BBC report, 68% of the land currently is used for livestock. With years of integration this could be cultivated as agricultural land. Also according to that same report, if the world went vegetarian the world's mortality rate would decrease by a significant amount. However, there are certain economic and sociopolitical drawbacks that would happen. Here is a link to the article: www.bbc.com/future/story/20160926-what-would-happen-if-the-world-suddenly-went-vegetarian
Alas, we look to Elon Musk for his entrepreneurship.
Oh yes
do every plants do photosynthesis?
+Annie Kuo yes
I lost track a minute into the video
imagine the lizard moaning
