Text Solution

Verified by Experts

The correct Answer is:
D
The green scum seen in water bodis includes both green algae as well as blue-green algae. The excessive growth of such bloom forming algae is mainly body (eutrophication). Such algal blooms can choke the water body. Green algae and blue-green algae (cyanobacteria) both ar photosynthetic and decrease the dissolved oxygen of water body. This kills much of flora and fauna of that water body. Later on, when microorganisms decompose these algae, further reduction in dissolved oxygen occurs.
