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