Question
Give reason.
Equilibrium is necessary in the various bio-geo-chemical cycles.
Solution
The cyclic flow of nutrients within an ecosystem is called as the biogeochemical cycle. A continuous transfer of nutrients which are necessary for the growth of organisms occurs from abiotic to biotic factors and biotic to abiotic factors in an ecosystem. This nutrient cycle operates continuously through the biosphere formed by lithosphere, atmosphere and hydrosphere. The recycling of these biogeochemicals depends upon the level of energy transfer in the ecosystem. Any type of disturbance at any level of these cycles affects the ecosystems and nature's balance. Hence, there should be equilibrium in the various biogeochemical cycles.
