Question

Why equilibrium is necessary for various bio Geo chemical cycle

Answer 1

In Earth science, a biogeochemical cycle or substance turnover is a pathway by which a chemical substance moves through both the biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) components of Earth. A cycle is a series of change which comes back to the starting point and which can be repeated.[1][2] Water, for example, is always recycled through the water cycle, as shown in the diagram. The water undergoes evaporation, condensation, and precipitation, falling back to Earth. Elements, chemical compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another through biogeochemical cycles

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.
