Nutrient Cycling
- The organisms need a constant supply of nutrients to grow, reproduce and regulate various body functions.
- The amount of nutrients, such as carbon, nitrogen, phosphorus, calcium, etc., present in the soil at any given time, is referred to as the standing state.
- It varies in different kinds of ecosystems and also on a seasonal basis.
- The nutrients are never lost from the ecosystems, they are recycled time and again indefinitely.
- The movement of nutrient elements through the various components of an ecosystem is called nutrient cycling.
- Another name of nutrient cycling is biogeochemical cycles (bio: living organism, geo: rocks, air, water).
- Nutrient cycles are of two types:
- Gaseous
- Sedimentary
- The reservoir for gaseous type of nutrient cycle (e.g., nitrogen, carbon cycle) exists in the atmosphere.
- The reservoir for sedimentary cycle (e.g., sulphur and phosphorus cycle), the reservoir is located in Earth’s crust.
- The function of the reservoir is to meet with the deficit which occurs due to imbalance in the rate of influx and efflux.
