The effects of eutrophication can be bad for ecosystems. When the over excess of algee in the lake or pond falls to the bottom, decomposers will decompose the material. Decomposers need oxygen to decompose and because of the amount of excess plant there is there is not enough oxygen left in the body of water to sustain all the life.

Eutrophication is the over abundance of nutriets in a body of water. It is most commonly caused by ferilizer runoff water entering ponds or lakes from farms. This is because phosphorus which is a main component in fertilizer increase plant growth and when it enters bodies of water is contributes to more plant growth in the form of algee.

11 represents the amount of phosphate in the fertilizer. As stated earlier, the phosphorus helps the plant grown but it also helps form new roots, seeds and flower. Along with all of this, it also helps the plants fight disease.

0 represents the amount of potassium in the fertilizer. Potassium is essential to fertilizer because it helps the plant grow stong stems and to grow at a fast rate.

24 represents the amount of nitrogen in the the fertilizer. Nitrogen is essential to fertilizer because it allows for a lot of leaf growth and good green color.

Phosphorus Cycle

Some of the phosphorus gets buried in sedimant and overtime this sediment forms rocks and the process repeats itself.

When these plants and animals die, decomposers are able to turn the phosporus inside them from organic matierial into inorganic matierial.

Humans have affected the phosphorus cycle by adding phosphorus to fertilizer to help plants grow. This can be neagtive however, because an over ubundance of phosphorus can result in the overgrowth of algee.

Plants are able to absorb the phosphorus and then grow.

Animals that eat these plants or drink the water where the phosphorus has run off also absorb phosphorus.

Weathering along with rain break down these rocks which results in the phosphorus to enter water and soil.

Phosphorus is stored in rocks.
