Question

Equilibrium is necessary in the various bio-geo-chemical cycles.

Answer 1

he most important biogeochemical cycles are the carbon cycle, nitrogen cycle, oxygen cycle, phosphorus cycle, and the water cycle. Thebiogeochemical cycles always have a state of equilibrium. The state ofequilibrium occurs when there is abalance in the cycling of the elements between compartments.

Answer 2

Explanation:

i. Human activities on the large scale such as clearing forest or cutting of trees on large scale (deforestation), burning of fossil fuels, more use of chemical fertilizers, and pesticides.

ii. These activities disturb the biogeochemical processes, directly or indirectly.

iii. Some steps should be taken to maintain the biogeochemical equilibrium in the ecosystem such as:

1. Plant more and more trees to maintain oxygen and carbon dioxide balance in nature.

2. Least use of chlorofluorocarbons.

3. Reduce vehicular pollution.
