Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The more diverse an ecosystem, the more ____ it is.
A
Biodiverse
B
Stable
C
Sustainable
D
Bright
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -The two key components of ecosystem stability are resilience and resistance. Resistance is an ecosystem’s ability to remain stable when confronted with a disturbance. Resilience is the speed at which an ecosystem recovers from a disturbance.

Detailed explanation-3: -In 1972, Robert May showed that diversity is detrimental to an ecosystem since, as the number of species increases, the ecosystem is less stable. This is the so-called diversity-stability paradox, which has been derived by considering a mathematical model with linear interactions between the species.

Detailed explanation-4: -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.

Detailed explanation-5: -In ecology, an ecosystem is said to possess ecological stability (or equilibrium) if it is capable of returning to its equilibrium state after a perturbation (a capacity known as resilience) or does not experience unexpected large changes in its characteristics across time.
