- Enter a kelp forest and explore the various threads that connect species together in food webs.
How do changes in the ecosystem effect the community? Enter an underwater forest of kelp and explore the various threads that connect species together that help maintain diversity and balance in food webs.
In addition to showcasing live footage from a unique ecosystem, each of the three videos in the Exploring Ecosystems series features an opportunity for students to actively participate in a problem-solving scenario based on an ongoing research project of Academy scientist Peter Roopnarine.
As you watch the video, be prepared to pause at key points to participate fully! Explore food webs through the kelp forest featuring sea otters (Enhydra lutris), sea urchins (Echinoidea), sea stars (Asteroidea), sunflower seastars (Pycnopodia helianthoides), abalone (Haliotidae), and other marine animals.
The Coastal Food Web video investigates the following questions:
How do you predict the effects of a change in the community’s populations on the community as a whole?
How will a change in an ecosystem affect energy flow, nutrient cycling, population growth, or community structure?
How will loss of an organism from a food chain or web affect flow of energy?
Check for Understanding
Describe two concrete examples of community interactions, being sure to describe the relationships between species.
Key Scientific Terms
community: two or more different species occupying the same geographical area and interacting in some way
ecosystem: the community of different species in a particular geographic area and all of their interactions with each other and the physical environment; ecosystems are also called ecological networks
herbivore: an animal that eats plants; also called a primary consumer
population: all the individuals of a particular species that live in a specific geographic area; a species may be made up of one or more populations
predator: an organism that hunts, catches, kills, and eats other animals
prey: an organism that is caught, killed and eaten by a predator
species: a distinct type of organism
Connections to High School Standards
AP Biology
LO 4.13: The student is able to predict the effects of a change in the community’s populations on the community.
(1) Interpreting graphs and other quantitative data that represent community and ecosystem interactions.
(2) Reading curves that represent community interactions (e.g., predator-prey) and using them to infer relationships between species.
(1) Working with ecological models and using them to predict how a change in an ecosystem will affect energy flow, nutrient cycling, population growth, or community structure.
(2) Predicting how loss of an organism from a food chain or web will affect flow of energy.

My teacher has me watching over 20 videos like this, and write detailed notes for all of them. Taking almost 2.5 hours now, when my science class should just take 45 minutes
litterally same
same I have sepnt 4 hrs it is 30 slides with 3 videos
Put in the effort to learn more earlier, you'll appreciate it later. More and more keeps connecting the older you get.
😄 attention deficit is the enemy, but coffee is a friend.
I had to do like 40 vids it took like 6 to 7 hours
@@chloepahoehoemine is 20 pages with 10 or sum vids . and im sick 😀
The animation was very realistic and phenomenal! And the graphics and visuals assisted with understanding of the topic quite a bit; great work.
thank you so much this makes science so much more easier, and i love how the animations look so real!
To any and all teachers reading this. Please ease up on your students. We're surviving a global pandemic, and a lot of us would like some time to ourselves. This pandemic has messed a whole ton of us mentally though a lot of us would not like to admit it. What a lot of us would want is to not have so much stress knowing we have assignments due but have no motivation or energy to do them. We are all so tired. Please understand we are only human and were children. We have lives outside of school, and we know you do too! Notice not every little subject needs an assignments, classwork, and homework. We understand you want to make sure we're learning as much as possible especially if we are virtual. I ask of you to please take my words into consideration.
💯.
for everyone that needs it:
Elements of the Oceanic ecosystem include animals (sea otters, fish, sharks, etc.), plants (Kelp and sea urchins), and microscopic algae.
I will reply for other questions and answers yall need i hate school too its fine
Tysm
you dropped your 👑
ey I know this is 8 months old, but I’m wondering if you could write about 3 interesting facts about the marine food web? Thanks! Also this is due today, so plz reply quickly.
I’ve also been looking for a couple of hours, but this is taking too long. thanks again
wait just found out that this needs to come from a source, like a website
The otters are just vibing on the surface
i had to watch this for online school and i loved it
Me too
Sameee

Yessir
My son needed this for school ,thank you.
This video does a phenomenal job of summing up food webs, and was a perfect supplement to my instruction in my biology classes. Thank you!
Had to help my grandson with his work during lockdown. His work included creating a diagram of the food chain. Your video helped immensely. Thank you.
I'm using this video for a science project, this is perfect :D
Thank you for the video
Good movie!
Very good video
Very nice video, thank you
As a Teacher - can I get the graphics of the food web? As a still? I think middle school will need more processing time.
ayo dont give ur students homework for a week and tell them to thank me
this vid is so cool
1:49 is my favorite bit
How come?
LOL I like this video

Hey high school students forced to take notes
Sup
I’m doing this for 4th grade
@@iiglazeddonutsii5931 Damn you must be in like a Honors class for Honors students
yoo
Yes
I would take 2 marks off your graph - lack of zero point and lack of title
Cerritos College gang wya.
8th grade living environments gang LMAO
It's helping me out with my science test
no
There's always a bigger fish
Cool
The spiny purple sea urchin is a _ in this ecosystem, because it eats the kelp.
a.) producer
b. tertiary consumer
c. primary consumer
d. secondary consumer
yall this one of my questions can yall help? ASAP
Hey I’m Fang’s C
Wow
Same
Did you guys know about candis. She died
Hi Bio people
Great job BUT .... is that sea floor greatly depleted (I don't know the area)... also you MUST please include diatoms and plankton in the food chain, without them none of this exists. Diatoms also provide 20% of the worlds CO2 to O conversion and ironically its burning the ancient diatom accretions of oil and gas that have led to their and our impending demise. Seventy percent of our oil and gas is of diatom origin. The irony is tragic. Diatoms are miscoscopic and to paraphrase trump "Who would have tought something so small was so important" ....

This is also why if eco systems get destroyed than agricultural gets destroyed, if agricultural gets destroyed humans have to go back to hunter-gatherer lifestyles, and if those eco systems get destroyed, we go extinct. It's all connected.
Someone should just summarise the whole video so we don’t have to watch it
I hate school videos they are soooo boring
Hi Sam
nice pretty video u did sience rocks!
olo
doo doo ca ca
yes
Where is the plastic?
lol
First
Sorry I had 2
Can we not say "first"? It's an educational video and saying "first" is not the point.
what happens when corporations dump radioactive waste into your beautiful habitat?
@2024-Rex Denger WOAH
It’s lux
Lol
Sam it’s lux
my teacher force me and my friends watch this video...
