43.	Define Nutrient cycling. Give the types of Nutrient cycling.
Answer» Nutrient cycling: The movement of nutrient elements through the various component of an ecosystem is called nutrient cycling. Nutrient cycles are of two types: (i) Gaseous cycle (ii) Sedimentary cycle. The reservoir for gaseous type of nutrient cycle (nitrogen, carbon) exists in the atmosphere. The reservoir for sedimentary cycle (sulphur, phosphorus) is Earth‘s crust. Environmental factors like soil, moisture, pH temperature regulate the rate of release of nutrient into the atmosphere. The function of the reservoir is to meet the deficit which occurs due to imbalance in the rate of influx and efflux.
