Question

Which cycles are operated in environment? What is their importance?

Answer 1

The environment has bio-geochemical cycles, which are of two types: gaseous cycles, such as the nitrogen and oxygen cycles, and sedimentary cycles, such as the phosphorus cycle.

Importance of Bio-geochemical Cycles:

1. Plants need water, carbon dioxide, phosphorus, potassium and nitrogen as nutrients, while animals require carbohydrates, proteins and fats.
2. After the death of producers and consumers, decomposition takes place, and the released elements mix with the soil.
3. The cyclic movement of nutrients occurs through biogeochemical cycles.
4. Elements such as carbon, nitrogen, and phosphorus move in cycles on earth.
5. Biogeochemical cycles help maintain the balance of the environment.
6. Human existence is possible only when the environment remains in a proper condition. Therefore, it is our responsibility to protect nature and maintain the balance of the environment.
7. The earth is not an ancestral property but a legacy borrowed from future generations. Hence, we must conserve it for ourselves and future generations.
