How is biodiversity important for ecosystem functioning?
Advertisements
उत्तर
Biodiversity is of utmost importance for maintaining standard ecosystem functions and serves as an insurance policy against environmental changes or rare events that could impair those functions. Directly, rich biodiversity is vital for managing ecosystems, executing habitat restoration, and assisting in landscape planning. Furthermore, through long-term ecosystem experiments, David Tilman concluded that increased diversity directly contributes to higher productivity. Ultimately, rich biodiversity is not only essential for overall ecosystem health but is also imperative for the very survival of the human race on this planet.
