Given below are two statements. One is labelled Assertion(A) and other is labelled Reason(R).

Assertion (A): Communities with more species tend to be more stable than those with less species.

Reason (R): Biotic community with more species is able to resist occasional disturbances.

In light of the above statements, choose the correct answer from the options given below.

High biodiversity leads to an increase in interactions between species, and many of these interactions have a positive effect on the ecosystem because they are mutually supportive. For example, a new plant species in a community may provide food for insect species, harbor fungi in its roots, and afford shade under which still another plant species may grow. Such interactions, though perhaps insignificant in themselves, can make the ecosystem as a whole more stable by preventing other plant or insect or fungal species from overgrowing. More balanced ecosystems are more likely to remain in balance. They are also more likely to recover successfully from environmental disruptions such as fires, storms, and floods.
