Algal bloom

Vedclass · Answer

(A) The image shows a dense growth of algae covering the surface of a water body,which is a classic example of an algal bloom. Algal blooms occur due to the excessive growth of planktonic (free-floating) algae,often caused by the enrichment of water bodies with nutrients like nitrogen and phosphorus (eutrophication). This phenomenon leads to the deterioration of water quality and can cause fish mortality and depletion of dissolved oxygen.
