NEET BIOLOGY

Detailed explanation-1: -The same atoms are recycled over and over in different parts of the Earth. This type of cycle of atoms between living and non-living things is known as a biogeochemical cycle.

Detailed explanation-2: -biogeochemical cycle, any of the natural pathways by which essential elements of living matter are circulated. The term biogeochemical is a contraction that refers to the consideration of the biological, geological, and chemical aspects of each cycle.

Detailed explanation-3: -Each biogeochemical cycle has two phases, namely the biotic phase (organic phase) and the abiotic phase. (i) Biotic phase : It refers to the flow of chemicals in the living organisms through food chain. (ii) Abiotic phase : It refers to the distribution and flow of chemicals in the non-living environment.

Detailed explanation-4: -Some examples of the biogeochemical cycles are the phosphorus cycle, oxygen cycle, carbon cycle and nitrogen cycle. Human activities have different impacts on the various biogeochemical cycles.

Detailed explanation-5: -A biogeochemical cycle is a pathway by which a chemical substance moves through both biotic and abiotic components of the earth. Biological, geological and chemical factors are all involved in pathways through which chemical nutrients like carbon, oxygen and nitrogen circulate.
