• A. They are easiest to experiments with.
• B. They can be grown in large tank cultures.
• C. They may form important constituent of human food (diet) in future.
• D. They produce oxygen and organic acids.

Answer 1

The correct option is C They may form important constituent of human food (diet) in future.

Algae are important as primary producers of organic matter at the base of the food chain. They also provide oxygen for other aquatic life. Algae may contribute to mass mortality of other organisms, in cases of algal blooms, but they also contribute to economic well- being in the form of food, medicine and other products. In tropical regions, coralline algae can be as important as corals in the formation of reefs. They may form important constituent of human food (diet) in future. In future when world population will be very much, to provide them all nutritious food, algae will be used as alternate source of energy.
