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: -Increasing species diversity can influence ecosystem functions-such as productivity-by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.
Detailed explanation-3: -Ecological life support-biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Recreational-many recreational pursuits rely on our unique biodiversity, such as birdwatching, hiking, camping and fishing.
Detailed explanation-4: -Higher number of species leads to greater stress resistance Systems with a higher number of species can thus keep their biomass production stable for longer than those with less biodiversity.
