There are certain elements that serve as food for living things such as trees and underwater plants. These are nutrients that help them grow, such as... phosphorous, nitrogen, etc. Just like humans can get sick from consuming too much, so can plants. This makes them grow at a rate higher than normal, not allowing the ecosystem in the water to work the same. Fish may not be able to swim in open water because the plants in the water are so overgrown. These excess elements in the form of food for the plants, usually come from waste from factories and stuff like that. So that is why the speaker talked about trash. Eutrophication is when a body of water becomes extremely filled with those plants, phytoplankton, etc. and there is not enough space for "normal conditions" for fish, humans, and other living organisms! I Hope this helped :)

@Harani66 2 жыл бұрын

water = Hydrogen+Oxygen so when fish "breathe" are they breaking the chemical bonds in water to extract oxygen ( and liberate hydrogen) or are they only ever pulling out free oxygen that is mixed into water ( not part of it)

Really well done. I'd like to know though how much of the 'trash' is chemical (fertilizers) or animal waste runoff from agriculture vs. population centers (storm runoff, untreated sewage). The garbage truck image is misleading. I'd guess very little of the 'trash' is what we typically think of as trash: plastic, paper, etc.

Could you please let me know why boiled water doesn't contain dissolved oxygen in it?

@lepidlover0557 5 жыл бұрын

Because it's too hot. The hotter a liquid is, the less dense it is, therefore the less oxygen it holds.

If the oxygen the plants produce is consumed when the plan dies, the fact that the plants are many or few doesn't change the oxygen content of the water and it is incorrect to say that plants are one of the ways in which oxygen is introduced into the water, because those plants will die in the water in any case.

I thought animals "breathe" in the oxygen from the water molecule, itself. Water is H2O. I thought they just took the O, and the hydrogen would evaporate until it joined with more oxygen to become water again. I don't have a clear understanding of how dissolved oxygen doesn't connect to the H2O molecules and become h2o2. Or, for that matter, why other molecules (like nitrogen) don't connect with the H2O molecules when they enter and dissolve in water.
