Question

Which of the following activities can destroy an ecosystem?

• A. Cutting down forests to build cities.
• B. Conserving the existing forests.
• C. Hunting animals and destroying plants.
• D. Adding excessive fertilisers to the land.

Answer 1

Answer: (A), (C), (D)

The correct options are
A Cutting down forests to build cities.
C Hunting animals and destroying plants.
D Adding excessive fertilisers to the land.

$\bullet$ An ecosystem is formed by the interaction of biotic and abiotic components.
$\bullet$ Any activity that harms either of the components, harms the whole of the ecosystem.
$\bullet$ Cutting down trees and plants, hunting animals, destroying the quality of crops by adding excessive fertilisers, etc., harms both the components and hence harms the ecosystem.
$\bullet$ On the other hand, planting more trees, conserving forests and natural resources like water and soil can help in conserving ecosystems.
