Question

How does a forest as an ecosystem is self sustaining?

Answer 1

An ecosystem is a self sustaining and self regulating unit in the environment. Forest ecosystem is a major unit of the terrestrial ecosystem. These are dominated by trees growing at minimum of 2m height together with native wildlife species. Nonliving things like water, soil and air interact with the living components. 

Answer 2

ΔŇŞŴ€Ř:

• ❇️ The soil of forests also gets naturally replenished by the decomposition of dead organic matter. Decomposers feed on this dead, decaying matter and convert it into dark coloured, nutrient - rich substance called humus. In this way, the nutrients are returned to the soil and are again used by plants and trees to develop food for animals. A forest is hence said to be self sustaining.
