Question

What does eutrophication mean? A simple definition of it

Answer 1

Eutrophication is the increase in chemical nutrients in an ecosystem, leading to overgrowth of algae and negative effects on water quality and plant and animal populations.

Step-by-step explanation:

Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases the primary productivity of the ecosystem. This occurs when excessive amounts of nitrogen and phosphorus, often found in fertilizers, enter a body of water. Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases the primary productivity of the ecosystem. The excessive nutrients lead to an overgrowth of algae, which can result in oxygen depletion and reduced water quality, negatively impacting fish and other animal populations.

Answer 2

A (very) brief definition of Eutrophication is the over-enrichment of a river or lake with nutrients, typically as a result of surface run off from nearby fields that have been fertilised artificially.

This leads to excessive algae growth, which, through a lot of steps, basically kills everything in the lake.
