Question

Define eutrophication. What are its adverse effect on the ecosystem

Answer 1

The process by which a body of water becomes enriched in dissolved nutrients (such as phosphates) that stimulates the growth of aquatic plant life which usually results in depletion of dissolved oxygen.

Its adverse effect on environment:

• Increased production of algae and aquatic plants.

• Lack of oxygen in water body.

• depletion of fish species.

• deterioration of water quality

Answer 2

Answer:

Oxygen is a byproduct of photosynthesis and, correspondingly, carbon dioxide the byproduct of respiration. Trees are often credited as the major oxygen generator for the planet, but that would be false. Most of the planet is covered with water and the collective photosynthesis of lowly algae is the true oxygen machine.
