As aquatic matter dies and settles in the pond, the microbes use up the oxygen as they decay.
they come from aquatic animals droppings
Aquatic plants and animals live together in the pond because they both bond in the their same environment to either help each other with benefit or even provide a home.

Eutrophication
Eutrophication is the build up or pile up of all sorts of nutrients. Which is phosphates and nitrates(waste) of animals. Eutrophication can change the pond by making it healthier because a lot of animals keep feeding off of it while it keeps reproducing itself.
well they will suck water and die.

nutrients, particularly nitrogen and phosphorus. High levels of dissolved nutrients can lead to excessive algae growth, a phenomenon known as eutrophication, which can have negative impacts on water quality and ecosystem health. Controlling nutrient inputs can help manage algae growth in aquatic systems.
In the case of fish in a pond, completely submerged plants are helpful in that they add oxygen to the water and offer a food source. They also add oxygen to the air surrounding the pond for lunged animals that live there.
A pond habitat is not just the water, its everything around the water too. THis is becdause everything near the pond use it as a main source for water.
