How does the biodiversity of an ecosystem affect its ability to withstand environmental stress?

The stress which occurs in the ecosystem are high temperature and salt concentration in the soil. So if the ecosystem has maximum biodiversity, there will be less affect on the ecosystem because the organisms which lives in that ecosystem show resistance against these stresses.

With the increase of biodiversity of the ecosystem, also increased the resistance against the stress and if the biodiversity decreases in the ecosystem, the ecosystem is greatly affected by the stress.
