The quantity of materials required for life such as oxygen, carbon dioxide, nitrogen, minerals, water, etc. are limited therefore there is a cyclic exchange of material between organisms and their non-living environment. The movement of material so living and non-living components of the biosphere are cal nutrient cycles/ biogeochemical cycles. Let's test your knowledge about Nutrient Cycling Biogeochemical Cycle in Ecology Quiz.
