The presence of more species with different adaptations makes it more likely that some organisms will survive an ecological disaster.

|
Greater genetic variation within species makes it more likely that some individuals will survive a disease outbreak.

|
|
The presence of a variety of herbivore species that can feed on a large number of different producer species helps ensure abundant prey for predators in the ecosystem.

Detailed explanation-1: -Tropical rain forests have the greatest biodiversity of any type of land ecosystem. How does biodiversity contribute to the sustainability of an ecosystem? A. The presence of more species with different adaptations makes it more likely that some organisms will survive an ecological disaster.
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: -Tropical rainforests are unique in the high levels of biodiversity they exhibit. Around 40% to 75% of all biotic species are indigenous to the rainforests. Rainforests are home to half of all the living animal and plant species on the planet. Two-thirds of all flowering plants can be found in rainforests.
