Diversity and biological balance may influence the functioning and stability of ecological systems. Scientists generally agree that as the number of species in any particular type of ecological system declines, that system can potentially lose its resilience. Biodiversity is the variety of life forms in an ecosystem. An ecosystem that is rich in biodiversity stabilizes the net productivity and makes the ecosystem more resistant to exotic species. It maintains the ecosystem by maintaining the food chain. The biodiversity provides raw materials for the survival of the livelihood within it. Soil fertilization, nutrient recycling, pest and disease regulation, erosion control, and crop and tree pollination are all provided by biodiversity. Biodiversity is the name given to the variety of ecosystems species and genes in the world or in a particular habitat. It is essential to human wellbeing, as it delivers services that sustain our economies and societies.
Biodiversity is the variety of life forms in an ecosystem. An ecosystem that is rich in biodiversity stabilizes the net productivity and makes the ecosystem more resistant to exotic species. It maintains the ecosystem by maintaining the food chain. 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. The greater the amount of genetic and species variation in an ecosystem, the more resilient that ecosystem is to disturbances. Variation in ecosystems across the Earth also contributes to the Earth's resilience to unpredictable changes.Ecosystems weakened by the loss of biodiversity are less resilient to climate change. In turn, climate change degrades habitats, further accelerating threats to species' survival. Biodiversity consistently increases resistance; however, biodiversity effects on resilience depend on the direction and duration of climate events. Ecosystem resilience is the ability of an ecosystem to absorb change and return to the same equilibrium state after a temporary disturbance. Ecosystems with higher species diversity tend to be more resilient. 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.
