If there were no plants and animals in the water, there would be an abundance of bacteria. Many plants and animals help to keep down bacteria growth in waters.

Bacteria in the soil break down organic matter into nutrients that plants can absorb, such as nitrogen and phosphorus. This process, known as decomposition, releases these essential nutrients back into the soil, enriching it and helping plants grow. Additionally, some bacteria form symbiotic relationships with plants, such as nitrogen-fixing bacteria that convert atmospheric nitrogen into a form that plants can use.
Nitrogen-fixing bacteria
Usually we worry more about bacteria attacking and destroying plant tissues, but some flowering plants do have a deal worked out where bacteria can help them, especially in the soil, and if bacteria are where they shouldn't be, plants have a sort of immune system which destroys the offending invader.
The bacteria in leguminous plants that form a symbiotic relationship with the plant are called rhizobia. These bacteria help the plant fix nitrogen from the air into a form that can be used by the plant for growth, and in return, the plant provides sugars to the bacteria.
Nitrogen-fixing bacteria help cycle nitrogen through the ecosystems in a variety of ways. With plants, the nitrogen-fixing bacteria help ensure that nitrogen is cycled back into the soil.
(i) De composer bacteria help in decomposing matter in the soil. (ii) It helps to maintain fertility in soil. (iii) Bacteria like cyanobacteria help in nitrogen fixation.
The bacteria feed on the waste and use the oxygen. (Straight from a Science Book.)
