Why does biodiversity contribute to a habitat’s sustainability?
A
The more plants and animals in a habitat, the greater the biomass, which is how habitats store energy.
B
The greater the number of species, the more competition there is for food between predators, which sustains their populations.
C
Changing conditions that harm one species leave other species to survive and perhaps even thrive.
D
Landforms change shape less frequently when there is a greater number of species using the land.
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Biodiversity is essential for sustainable development and human well-being. It underpins the provision of food, fibre and water; it mitigates and provides resilience to climate change; it supports human health, and provides jobs in agriculture, fisheries, forestry and many other sectors.

Detailed explanation-3: -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-4: -Biodiversity contributes to the sustainability of a habitat since a healthy ecology features many trophic levels of producers, consumers, and decomposers. More biodiveristy at any such niche supports each other niche: more diverse plant life leads to more diverse herbivores and in turn more diverse carnivores.

Detailed explanation-5: -The relationship between biodiversity and sustainability is direct. Biodiversity is the variety of species living in an ecosystem. Areas with high biodiversity have more complex interactions between organisms, and this complexity helps the ecosystem maintain homeostasis.
