Question

The snakes are included under

• A. Saprophytes
• B. Primary consumers
• C. Second trophic level
• D. None of the above

Answer 1

The correct option is D None of the above

All animals depend on plants (directly or indirectly) for their food needs.They are called as consumers and also heterotrophs. If they feed on the producers, they are called as primary consumers, and if the animals eat other animals, which in turn eat the plants, they are called as secondary consumers. In a terrestrial ecosystem one food chain can be-
Grass -.> Grasshoppers -> Frog -> Snake -> Pea Cock/ Falcon/ Eagle.
In this case insects will be primary consumers, frog will be secondary consumer, snake will be tertiary consumer and birds like falcon/ eagle/ peacock will be quaternary consumers.
