Which of the following statements is not correct regarding algal bloom...
Explanation:
Algal blooms are excessive growth of algae in water bodies. The correct statement among the given options is:
b) Growth of Eichhornia crassipes causes colouration of water during algal blooms.
This statement is not correct because Eichhornia crassipes, commonly known as water hyacinth, is a floating aquatic plant that can grow rapidly in nutrient-rich water bodies. It is not a type of algae and does not directly contribute to the formation of algal blooms. However, the growth of water hyacinth can indirectly contribute to the growth of algae by blocking sunlight and reducing dissolved oxygen levels in the water.
The other statements are correct:
a) Algal blooms are formed by blue-green algae: Blue-green algae, also known as cyanobacteria, are a type of photosynthetic bacteria that can form algal blooms in nutrient-rich water bodies.
c) Increased growth of algae causes depletion of O2 in water: During algal blooms, the excessive growth of algae can lead to depletion of dissolved oxygen levels in the water, which can harm aquatic organisms such as fish and other animals.
d) Algal blooms cause deterioration of water quality and fish mortality: Algal blooms can contribute to the deterioration of water quality by reducing dissolved oxygen levels, increasing turbidity, and releasing harmful toxins. This can lead to fish mortality and other negative impacts on aquatic ecosystems.
