Question

Snakes, eagles, grasshoppers and frogs are a part of a food chain. If 600 J of energy is available to the eagles, how much energy (in J) is approximately available to the frogs?​

Answer 1

Explanation:

In a food chain, consumers are categorised into three groups: primary consumers, secondary consumers, and the tertiary consumers.

The primary consumer is the grasshopper, feeding on grass which are the producers. Secondary consumers are frog.

Tertiary consumers are the snake and the last consumer is the eagle.

According to the ten percent law, exactly 90% of the energy is lost in the transfer at each trophic level, and only 10% is passed on as usable biological energy.

Here, the frog has the more energy than the tertiary consumer and less than the primary consumer.
