Question

How food chain gets shortened?

Answer 1

Reason for food chain getting shortened:

1. Human activities such as tree cutting and wild animal hunting weaken food chains. This throws the ecological system off-kilter.
2. A large rise in the number of individuals of one species is offset by a large drop in the number of individuals of another.
3. It disrupts the ecosystem's and biosphere's normal functioning.
4. If organisms from one trophic level are removed, organisms from the next trophic level will prosper and expand in number.
5. While species from the next trophic level will dramatically decline, resulting in an imbalance.
