Stability of a community depends upon its species diversity' Justify the statement.

Explanation

(i) Species have been evolving and becoming extinct since the orgin of life. But species are now becoming extinct at a faster rate. This is destabilizing the ecological stability and the distribution of biological diversity on earth.
(ii) The current rate of biodiversity loss is 100 - 1000 times higher than the naturally occurring extinction rate. This loss of biodiversity will lead to loss in diversity of species. It has a huge impact on plant, animal and human life. The negative effect includes dramatic influence on food web. Even reduction in one species can affect the entire Food chain. This will affect the food sources of many species and will affect the stability of a community.
(iii) Many species may die due to lack of food. Thus species diversity will stabilise a community and also help the community to rebuild in case of any change/challenges faced by the community.
