Detailed explanation-1: -Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species. Species diversity is all the differences within and between populations of species, as well as between different species.

Detailed explanation-2: -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-3: -To be invasive, a species must adapt to the new area easily. It must reproduce quickly. It must harm property, the economy, or the native plants and animals of the region. Many invasive species are introduced into a new region accidentally.

Detailed explanation-4: -Our global food system is the primary driver of biodiversity loss, with agriculture alone being the identified threat to 24, 000 of the 28, 000 (86%) species at risk of extinction. The global rate of species extinction today is higher than the average rate over the past 10 million years.
