briefly write about the variability of natural systems and the significance of the rate of change and predictability to the stability and functioning of ecological systems

Solution

Answer:- The natural ecological systems are usually variable in physical and biological characteristics that are always in dynamic equilibrium with their biota. The ecological systems which diverse both in eveness and richness of species are usually stable and less prone to extinction and resist the disturbances created by any external agency. The keystone species play an important role in the ecosystem functioning and overall community stability. Thus variability and stability are essential for functioning of ecological systems.
