Question

Arrange the following food chains in a proper sequence. (a) Small fish, Algae, Mosquito larvae, Kingfisher

Hint:

In food chains, the organisms are arranged according to their trophic levels, starting from producers (plants) to primary, secondary, and tertiary consumers.

Answer 1

The correct sequence for the food chain is:
{Algae → Mosquito larvae → Small fish → Kingfisher}

Step 1: Explanation of the Food Chain.
- {Algae} serve as the primary producers, forming the base of the food chain by converting solar energy into chemical energy through photosynthesis.
- {Mosquito larvae} feed on algae, making them primary consumers.
- {Small fish} feed on mosquito larvae, acting as secondary consumers.
- {Kingfisher} is a tertiary consumer that preys on small fish.
(b) Frog, Snail, Crow, Green leaves % Solution Solution:
The correct sequence for the food chain is:
{Green leaves → Snail → Frog → Crow}

Step 1: Explanation of the Food Chain.
- {Green leaves} are the primary producers that provide food for herbivores.
- {Snail} feeds on green leaves, acting as a primary consumer.
- {Frog} preys on the snail, functioning as a secondary consumer.
- {Crow} is a tertiary consumer that feeds on the frog.
