Question

Polluted water bodies have usually very high abundance of plants like Nostoc and Oscillitoria. Give reasons.​

Answer 1

Answer:

Polluted water bodies are rich in nutrients especially in nitrogen content which provides favourable condition to algae like Nostoc and Oscillotoria to bloom in the water bodies.....

Answer 2

Explanation:

➡️ Eutrophication of polluted water bodies is the reason behind this high abundance of plants like nostoc and oscillatoria in them. Polluted water bodies contain phosphates and nutrients like nitrogen that trigger the growth of algae hence these two sub-classes of algae grow in higher abundance in polluted water bodies.
