Eutrophication is a process where increased nutrient levels cause excessive primary production, leading to dense algal blooms. These blooms degrade water quality and can cause oxygen depletion upon decomposition, leading to fish kills.
Consider the following statements and choose the right options given below. (1) Presence of large amounts of nutrients in water also causes excessive growth of planktonic (free-floating) algae, called an algal bloom. (2) Algal bloom causes deterioration of water quality and fish mortality.
