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.
