Question

Easy availability of nutrients in aquatic habitat may lead to _____ (a) Biomagnification (b) Eutrophication (c) Mutation (d) Greenhouse effect

Answer 1

(B) Eutrophication because the definition is excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen :)

Answer 2

The availability of nutrients in aquatic habitat leads to Eutrophication.

The following are the process which lead the aquatic habitat to Eutrophication

· First, If the fertilizers are spread on a land.

· Then, the rain spreads the fertilizer in the soil, later, the soil absorbs it.

· Then, the fertilizer is transferred to a lake by the water which flows into the underground.

· The presence of water in the lake causes overgrowth of algae and aquatic plants.

· The overgrowth of aquatic plants does not allow the sunlight to reach the lake which causes algae to die.

· Then, the bacteria decompose the algae.

· While decomposing, the bacteria uses up all the oxygen in the lake making it anoxic.

· Due to this, all the living organisms in the lake or water resources dies.
