Question

Explain Productivity Stability Hypothesis.

✓

Answer

Productivity Stability Hypothesis emphasises the importance of species diversity to the ecosystem. This hypothesis was given by David Tillman.
It states that rich diversity leads to lesser variation in biomass production over a period of time and species richness is not needed for maintaining the stability of an ecological community.
If average biomass production remains fairly constant over a period of time, then that community remains stable.
The stable community remains strong to withstand disturbances and also recover quickly. Such community is resistant to invasive species.
