The Aquatic Environment: Marine and Freshwater
Вставка
- Опубліковано 17 жов 2024
- Water covers 70% of the surface of the Earth, and serves as home to an incredible variety of living organisms. Most of that water is salty, or marine, while some is freshwater, and it is in constant motion through the hydrologic cycle. How can we describe these environments and ecosystems?

Water is so important and common it’s almost like life evolved in the presence of it. But the discovery institute told me that’s just a coincidence. 😂😂😂
Hi, really appreciate your content in general, but the lagoon pic (at 7.35 mins) isn’t a natural lagoon. It’s in Pembrokeshire, Wales, UK. It was a slate quarry and when that ended it was blasted to make an inlet to harbour fishing boats. Now it is a swimming spot and has hosted the world cliff diving championships. Not sure it’s an appropriate example? But I may be wrong 😊 thanks
Water is pretty awesome.
Alas, the world's water supply has been contaminated with that killer chemical, Dihydrogen Monoxide.
Thank you for these fantastic educational videos. I use your videos with my most advanced English students (ages 9 to adult) in Vietnam. They are homework assignments with written or verbal Tests.
Naturally evolved Estuaries are so important but most are lost to something lesser now. I hope eventually the natural ones will be returned.
you are credit to science dave I have learnt a lot from you. Love your chanel
I love your contents so much
Am well loaded for ecology exams tomorrow 😊
Beautifully done, keep the educational lessons coming -,you’re great!
hey Dave, some new research is out there regarding the origins of water on Earth. or maybe not very new, but just discovered it this week
Thanks sir but may u do me a video while explaining the factors affecting the degree of oxygen in aquatic habitat
this is great, thanks
I just left this comment to let you that read this know you are amazing, everything will be ok. Even if you right now are struggling I know you can get through it, I believe in you ❤
Brilliant content.🤗
Hi cutie 😊
Is that ebola virus in the blood animation at 1:50?
Would you say chloride isnt found in 3 states because its bonded to sodium? The oxygen is bound to hydrogen dave. Youd be specific but limit ideas like the black sea makes people float. That excited me.
If we played these videos in class they
would actually figure out what the words mean but still forget it in three seconds
Immunology?
Great is the Creator 😊
لا إله إلا الله ❤
I keep saying it, drink more water.
The first part was funny 😂😂
Epic
If you haven't had any today, drink water. Not tea, not coffee, not some kind of flavored or sugar water. Drink water. Your body will thank you.
Everybody drinks water every day.
All those have lots of water in them lol. 🙄
Man, water is pretty.
❤❤❤
Don ?
I'm recycler, reuser and currently posion ivy Dave. Apparently I'm no longer immune to the devil's vine but I'm here to hear and the sheep ain't scared.
...What?
What?

You know, you don't HAVE to over-complicate literally EVERY phrase. We're not gonna call you an idiot for using the more simple or more commonly used terms, so just stick with those. It makes you sound a little less pretentious which a lot of us admittedly have a problem with.
He didn’t use any big words at all 😂😂
I have absolutely no clue what you're talking about. This is an ecology tutorial so I use the proper terminology.
He makes these videos for people in school. layman's phrases won't get you credit on a test. If you find scientific terminology complicated, I think thats more a problem with you.
Do you want him to say water is bigly?
A meat-eating environmentalist is one hell of an oxymoron if I ever saw one.
Animal agriculture is one of the leading causes of species extinction, habitat destruction, and climate change. More so than all transportation combined. Yet those on top, in power, keep harping on fossil fuels. It's easier to buy an electric car than to change eating habits and take responsibility for our actions.
A new comprehensive study from Oxford University clearly shows that a vegan diet is the best for the planet (and the non-human animals)
The change is simple. Be vegan.
Didn't ask
Didn't ask.
Not eating grass.
Not driving an electric scooter.
You worried about someone eating a damn hamburger when the world is under full on attack by Globalists who would kill you in a second if they could. When the global economy completely implodes in a few months exactly as planned you will be glad to get that hamburger.
When you're a hammer, everything appears to be a nail whether thumb or device for attaching cave trees together.
@@jeffk3352 So you prefer to be ignorant?
@@BlastedKat 😂
Yea, I eat burgers, burritos, curry, pizza, pretzels...I haven't had grass since I was curious what it tasted like as a child. Hell, I don't even remember the last time I had a salad. What's wrong with a manual scooter, skateboard, or bike?
Professor Dave do you believe in a god
