Question

Environmental balance is maintained by:

• A. Water cycle
• B. Gaseous cycle
• C. Food chains of the ecosystem
• D. Global warming

Answer 1

Answer: (A), (B), (C)

The correct options are
A Water cycle
B Gaseous cycle
C Food chains of the ecosystem

Environmental balance is maintained in the following ways:

• Through continuous operation of various natural cycles such as the water cycle, carbon cycle, oxygen cycle and nitrogen cycle.
• It is also maintained due to the existence of various food chains in the ecosystem. For example, if the population of pests such as grasshoppers isn't controlled by frogs or lizards that prey on them, pests start to manifest rapidly and destroy all crops, breaking the balance of the environment.
