How is biodiversity important for ecosystem functioning?

(N/A) An ecosystem with high species diversity is much more stable than an ecosystem with low species diversity. High biodiversity makes the ecosystem more stable in productivity and more resistant to disturbances such as alien species invasions and floods.
If an ecosystem is rich in biodiversity,the ecological balance is maintained. Various trophic levels are connected through food chains. If organisms of a specific trophic level are removed,it disrupts the entire food chain. For example,if all plants are removed,herbivores like deer will die due to lack of food,which subsequently leads to the death of predators like tigers.
Therefore,it can be concluded that if an ecosystem is rich in species,there will be alternative food sources at each trophic level,preventing the collapse of the food web. Hence,biodiversity plays a crucial role in maintaining the health and ecological balance of an ecosystem.
