Describe the sequential process of eutrophication.

Solutions

Expert Solution

The process of eutrophication are given below as :

1. Eutrophication is the aging of a lake caused by increased plant growth due to excessive nutrients. For example, if a lake is polluted with phosphorous, a key ingredient in fertilizers, it will cause the algae and other plant to grow faster and in abundance causing the lake to dry up. Eventually, area that used to be the lake can turn into a swampy area or a bog.

2. Eutrophication is a process in which bodies of water receive even more nutrients, usually nitrogen and phosphorous, that stimulate excessive growth of algae. They are usually introduced into the water by run-off from fertilisers from near-by fields.

#The sequential process of eutrophication are as follow -

a. excess nutrients enter waterways

b. nutrients promote plant growth, especially algae

c. algal bloom occurs

d. algae die and are decomposed by bacteria

e. decomposition of algae increase biological oxygen deman

f. there is a drop in oxygen levels

f. fish, macroinvertebrates and other aquatic life forms die
