Ecosystems that have high levels of biodiversity have a large number of species, complex food webs, a variety of ecological niches, increased genetic diversity, and abundant resources. Having a number of different organisms increases the stability of an ecosystem, because a change in the population of one organism will have less effect on the population of an organism that depends on it.

Un ecosistem este cu atât mai stabil cu cât biodiversitatea biocenotica este mai mare, deoarece fiecare componentă biocenotica este supusă mai multor presiuni din interiorul ecosistemului! Atunci când intr-un ecosostem, pătrunde un element alegem, ex.o specie invazivă exotică, consecințele pot fi catastrofale ptr.intregul ecisistem! Exemple sunt nenumărate în cest sens!

Dr Constantin Ciubuc thank you for your contribution to the discussion

Ecosystem stability is the ability of an ecosystem to maintain a steady state, even after a stress or disturbance has occurred. Having a number of different organisms increases the stability of an ecosystem, because a change in the population of one organism will have less effect on the population of an organism that depends on it. Greater biodiversity in ecosystems, species, and individuals leads to greater stability. As 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. That is, biodiversity can increase overall ecosystem stability when biodiversity is low, and decrease it when biodiversity is high, or the opposite with a U-shaped relationship. Biodiversity provides us with drinking water, oxygen to breathe, food, medicine, decomposition of waste, and helps our planet withstand natural disasters. Ecosystems that have high levels of biodiversity have a large number of species, complex food webs, a variety of ecological niches, increased genetic diversity, and abundant resources.
