Question

Which part of the given food chain is affected by the extinction of frog?

Grass $\to$ Grasshopper $\to$ Frog $\to$ Snake $\to$ Eagle

• A. The whole food chain is affected.
• B. Only eagles and snakes are affected.
• C. Only snakes are affected.
• D. Only producers and decomposers are affected

Answer 1

The correct option is A The whole food chain is affected.

In the above food chain, if the population of frogs decrease, it will directly affect snake since snakes feed on frogs.
If the population of snakes decline, it will affect eagles as they will also not get sufficient food for their survival.
Grasshoppers will increase in number if the population of frog declines as there wouldn't be enough number of predators for them. Grass population gets affected as a result of this.
Thus, the declination or increase in the population of any species in the food chain affects the entire food chain.
