An ecosystem that is not sustainable can break down when a natural disaster occurs. This can lead to organisms in the ecosystem either leaving the area or dying off.
Increased biodiversity results in a more sustainable ecosystem because -
A greater number of plant species means that there is less barren land
A greater variety of species present allows more organisms to adapt after changes occur
The transition area between two ecosystems is narrower.
There are fewer species to be affected by environmental stresses
Tropical rainforests have the greatest biodiversity of any type of land ecosystem. How does biodiversity contribute to the sustainability of an ecosystem?
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.
All of the above.
