Why does biodiversity contribute to a habitat’s sustainability?

• The more plants and animals in a habitat, the greater the biomass, which is how habitats store energy.

• The greater the number of species, the more competition there is for food between predators, which sustains their populations.

• Changing conditions that harm one species leave other species to survive and perhaps even thrive.

• Landforms change shape less frequently when there is a greater number of species using the land.
