Ans 1: Excessive growth of blue green algae due to high concentration of phosphates and nitrates in water is called algal blooms.
It can cause deficiency of oxygen in water and leads to animal death.

Question # 7

Differentiate between limnetic zone and profundal zone.

Ans 1: Limentic zone: In this zone adequate or enough light penetrates to support photosynthesis.In this zone mainly cyanobacteria,protozoa,small crustaceans and fishes are present.
Ans 2: Profundal zone: In this zone light is insufficient to support photosynthesis.This area is mainly nourished by detritus that fall from littoral and limnetic zone.Here mostly decomposers and detritivores like snail,certain insect larvae,bacteria,fungi and fish inhabit.

Question # 8
