What makes an ecosystem stronger so it is more likely to survive?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

What factors help in the stability of the ecosystem?
Factors affecting stability:
Disturbance frequency and intensity (how often and what kind of tillage) Species diversity (intercropping or rotations), interactions (competition for water and nutrients from weed species), and life history strategies (do the species grow fast and produce many seeds or slow with few seeds)
What is meant by ecosystem resilience what can cause it to fail?
What is meant by ecosystem resilience? What can cause it to fail? … If forests are removed from a landscape by human intervention and the area is prevented from undergoing reforestation by overgrazing, the soil may erode, leaving a degraded state that carried out few of the original ecosystem’s functions.
What is ecosystem stability?
Stability (of ecosystem) refers to the capability of a natural system to apply self—regulating mechanisms so as to return to a steady state after an outside disturbance.
