NEET BIOLOGY

Detailed explanation-1: -Matter flows through trophic levels and elements are recycled among ecosystems using biogeochemical cycles. As nutrients move through ecosystems, the compounds they form are usually transformed.

Detailed explanation-2: -Some of the major biogeochemical cycles are as follows: (1) Water Cycle or Hydrologic Cycle (2) Carbon-Cycle (3) Nitrogen Cycle (4) Oxygen Cycle. The producers of an ecosystem take up several basic inorganic nutrients from their non-living environment. These materials get transformed into the bio mass of the producers.

Detailed explanation-3: -A biogeochemical cycle (or more generally a cycle of matter) is the pathway by which a chemical substance cycles (is turned over or moves through) the biotic and the abiotic compartments of Earth. The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, hydrosphere and lithosphere.

Detailed explanation-4: -Biogeochemical cycles are a combination of biological, geological and chemical pathways. It is also known as an inorganic-organic pathway. Explanation: In this pathway, chemical elements move through living biological spheres or non-living/ abiotic spheres like atmosphere, hydrosphere or lithosphere in a cycle.
