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: -The ways in which an element-or compound such as water-moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.
Detailed explanation-3: -Importance of Biogeochemical Cycles These cycles demonstrate the way in which the energy is used. Through the ecosystem, these cycles move the essential elements for life to sustain. They are vital as they recycle elements and store them too, and regulate the vital elements through the physical facets.
Detailed explanation-4: -The nutrient cycle is a system where energy and matter are transferred between living organisms and non-living parts of the environment. This occurs as animals and plants consume nutrients found in the soil, and these nutrients are then released back into the environment via death and decomposition.
