Algal bloom occurs when waterbodies contain less nutrients in them. True or False?
Answers
Answer:
yes
Explanation:
The development and proliferation of algal blooms likely result from a combination of environmental factors including available nutrients, temperature, sunlight, ecosystem disturbance (stable/mixing conditions, turbidity), hydrology (river flow and water storage levels) and the water chemistry (pH, conductivity, ...
Answer:
True
Explanation:
Algal bloom is the rapid growth of algae in water due to which coloured scums are formed on the surface. It is formed due to eutrophication. Eutrophication is the phenomenon of nutrient enrichment of nitrogen and phosphorus in a water body that supports a dense growth of plants and animal life. Due to nutrient enrichment, excess growth of algae occurs which is called algal bloom. Hence, assertion is incorrect.
When these algae die, their organic matter gets decomposed and this results in the depletion of oxygen leading to death of aquatic animals. Hence, reason is also incorrect.
So, the correct answer is 'Both Assertion and Reason are incorrect'.
