Question

A group of students conducted a test in their laboratory at school to assess the quality of water collected from a nearby pond. They found the level of nitrates to be very high.

Hence, they concluded that it would lead to:

विकल्प

• an increase in the algal bloom.

• an increase in the oxygen level.

• a decrease in turbidity of water.

• a decrease in hardness of water.

Answer 1

an increase in the algal bloom.

Explanation:

Nitrates act as essential nutrients that accelerate the growth of aquatic plants. A high concentration of nitrates in a closed water body like a pond leads to rapid and excessive growth of algae, a process known as eutrophication.
