Explanation:

Species diversity is defined as the number and abundance of different species that occupy a location. Species diversity increases the number of links in the food web.
There can be various reasons for the stability of the ecosystem because of species diversity: Increased food web diversity increases the resilience of the system to outside invasions of exotic organisms and reduces the fluctuation in the population within a given ecosystem. A large number of interacting feeding links provides alternative channels for energy flow and thus is generated a wide variety of adjustments of the population to environmental changes and stresses within the ecosystem. Another reason is more stability of a natural ecosystem because as the community
succession operates, the homeostasis increases due to more protection available to the members of the community against external environment change.
