What is a Nutrient Cycle
A nutrient cycle is the movement of a nutrient through an ecosystem. These cycles include both biotic and abiotic components. The biotic components are all of the living parts within the cycle; including things that were once living. The aboitic components are all the nonliving parts within the cycle. The abiotic components act as reservoir where nutrients can be stored and taken from. Nutrient cycles can be local or global. You can see a full nutrient cycle taking place within an individual ecosystem, or you instead look at the movement of that nutrient through the entire world. Nutrient cycles can also be called biogeochemical cycles. This more specifically refers to the transfer of chemicals to and from the biosphere(living things), hydrosphere(liquids), atmosphere(gasses), and lithosphere(solids). Three of the most important of these cycles are the carbon, phosphorus and nitrogen cycle.
