Decomposers break down dead animals and plants. They usually benefit producers by releasing nutrients back in the soil.
That would be : adenine, thymine, guanine, and cytosine.
First of all, it makes algae grow, because pesticides and stuff provide too many nutrients. Algae needs a lot of oxygen and so the fish begin to die off because the algae is taking all the oxygen out of the lake. Next, it causes biodiversity to drop, meaning that species are beginning to get less varied. Water pollution harms the lakes and is a concern because the effects of it on species and the water will stay.
