An ecosystem that is not sustainable can break down when a natural disaster occurs. This can lead to organisms either leaving the area, or dying off.

Increased biodiversity results in a a more sustainable ecosystem because-

• a greater number of plant species means there is less barren land

• greater variety of species allows for more organisms to adapt to change

• the transition area between two ecosystems is narrower

• there are fewer species to be affected

Multiple Choice

Tropical rainforest have the greatest biodiversity of any land ecosystem. How does biodiversity contribute to the sustainability of an ecosystem?

• greater amount of species guarantees a higher amount of survival after a disaster

• greater genetic variation allows for survival in a disease outbreak

• variety of herbivore species that can feed on multiple different producers ensures abundant prey for predators

• all of the above
