Ecologists have shown that-
|
|
higher animal to plants ratios provides the most stable environment
|
|
|
having multiple keystone species is important to ecological stability
|
|
|
higher biodiversity in an ecosystem provides better stability
|
|
|
ocean ecosystems are far more stable than terrestrial ecosystems
|
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: -Biodiversity increases and decreases ecosystem stability.
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.
