Organic Matter

 Organic Matter. It can be the thing that makes or breaks an ecosystem. This is because almost all organic matter in a freshwater ecosystem is used as food for the many organisms. A few examples of organic matter are algae, plankton, bits of wood, and leaves. There is such a thing as having too much organic matter. Too much, and oxygen levels decrease (because of bacteria decomposing the organic matter and releasing CO2) Too few and organisms will have to move to get more food.

These fish died because of an excess of organic matter which used up more oxygen than was welcome.



Decomposing organic matter can also increase the amount of bacteria thus increasing the amount of CO2 then increasing the amount of algae and thus bringing more aquatic life to the area and starting the process over.
