Ecosystem Sustainability

The greater a habitat’s biodiversity, the greater will be that habitat’s -

• sustainability over time with varying conditions.

• consumption of energy in the form of sunlight.

• temperature ranges across the seasons.

• distance to the nearest water source.

Over time, a shallow pond fills with plants, such as duckweed and cattails. These plants –

• will die off quickly in the shallow water.

• support ecological succession from pond to marshland.

• will grow into larger trees as they mature.

• eventually will dry out and create a fire hazard.

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.
