Question

which problems will arise if there is either increase or decrease in number of any component of food chain or food web?

Answer 1

There will be imbalance of population in the food chain

The organisms feeding on the components decreased will also decrease in number

The organisms on which the component feed will increase in number.

Answer 2

To prevent the destruction of our environment,the balance among the number of components in a food chain is extremely necessary.

If a particular segment of the components of a food chain either decreases or increases then the upper or lower components will also decrease or increase.

This will affect the consumption rate of our environmental resources and it will ultimately cause a environmental disbalance among the various components of the ecosystem.
