Question

Observe the food chain given below:

What would be the effect on food chain if carnivorous disappear?

• A. Life will not be possible.
• B. The number of herbivores will increase rapidly.
• C. Grass will be more.
• D. There will be no ultimate source of energy.

Answer 1

The correct option is B

The number of herbivores will increase rapidly.

The food chain can be explained as follows:

Sun is the ultimate source of energy. In a food chain, energy enters through autotrophs. If all frogs disappear, number of grasshopper will increase and the grass available will be less. Plants are autotrophs that produce food by trapping solar energy. Without plants life is not possible. Carnivores obtain food from herbivores, the number of herbivores will increase that leads to reduced quantity of grass.
