An ecosystem is a natural unit of plants, animals, and microorganisms functioning together with all non-living environmental factors. To conserve this delicate balance, it is important to know what part each piece of the natural ecosystem does for all the others.Preserving any bionetwork can be very difficult, because it is almost impossible to know what each element of the ecological unit adds to the equation.o conserve this delicate balance, it is important to know what part each piece of the natural ecosystem does for all the others.

Resistance and resilience: the relationship between stability and sustainability. Ecosystem stability is an important corollary of sustainability. Over time, the structure and function of a healthy ecosystem should remain relatively stable, even in the face of disturbance.If a stress or disturbance does alter the ecosystem is should be able to bounce back quickly.n ecosystem disturbance can be natural or human induced stress. An example of a natural disturbance is a hurricane or a tornado. An example of a human-induced or anthropogenic disturbance is tillage or pesticide application. Redundancy in ecosystem structure and function often infers stability on a system.
