How can an increase in biodiversity lead to an increase in ecosystem stability?
a. a more biodiverse ecosystem is not subject to change.
b. a more biodiverse ecosystem has a higher chance of adapting to species changes.
c. a more biodiverse ecosystem has fewer species types to balance.
d. a more biodiverse ecosystem is subject to fewer natural disasters.

Biodiversity translates to the variety of species that exist within a set ecosystem. This can be both plant and animal life. A greater biodiversity is considered better as the different species are able to use and benefit from all the different types of environmental resources. This leads to a much more complex ecosystem that isn't reliant on fewer resources and in the case of environmental change can still prevail and adapt accordingly. Had they been reliant on fewer resources, any change to those few resources would have led to greater problems in the entire ecosystem.
