Question

The correct sequence of food chain is:

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

A food chain in an ecosystem consists of producers, primary consumers, secondary consumers and decomposers. Here, the producer is grass and the first consumer is the insect. The insect is eaten by a bird, a secondary consumer and the bird is eaten by a snake, which is a tertiary consumer. So the correct food chain will be grass, insects, birds and snakes. Decomposers are not mentioned in this food chain.
