Answer 2

ANSWER:

Ecological balance is disturbed by humans in several ways. Cutting of trees, hunting of animals, wastage of water and pollution are the major ways in which humans disturb the ecological balance.

EXPLANATION:

Ecological balance refers to a stable balance in the number of every species in the ecosystem. When humans hunt animals, the number of animals decreases leading to an imbalance in the ecosystem.

The cutting of trees to build roads, houses and bridges results in a decrease in the number of trees thereby disturbing the ecosystem.
