Question

Explain how eutrophication can change an aquatic ecosystem into a land ecosystem

Answer 1

In nature, eutrophication is a common phenomenon in freshwater ecosystems and is really a part of the normal aging process of many lakes and ponds. Some never experience it because of a lack of warmth and light, but many do. Over time, these bodies of freshwater change in terms of how productive or fertile they are. While this is different for each lake or pond, those that are naturally fed rich nutrients from a stream or river or some other natural source are described as "eutrophic," meaning they are nutrient-rich and therefore abundant in plant and animal life. Eutrophication is not necessarily harmful or bad, and the word itself is often translated from the Greek as meaning "well nourished" or "good food." However, eutrophication can be speeded up artificially, and then the lake and its inhabitants eventually suffer as the input of nutrients increases far beyond what the natural capacity of the lake should be.

Answer 2

Eutrophication is a natural phenomena which occurs because of the surface runoff of minerals and sediments inside the water body where the water flow remains static for example lakes and ponds. The settled deposits aids in the growth and abundance of aquatic plants which depletes the oxygen level in the water. The increase in the abundance of plants typically wild weeds acquire the entire space occupied by the water body and this leads to the transformation of the aquatic ecosystem into terrestrial or land ecosystem.
