• the variety of species on Earth
• nonrenewable resources
• the rate of species decline

Sustainability refers to

• how many species are present in an ecosystem
• when a species goes extinct
• how long a species lives
• the ability to maintain ecological process over long periods of time.

What is true about sustainability?

• Having a small number of species increases biodiversity

• Sustainability is how organisms change over time

• Sustainability is how much rainfall and sunlight an ecosystem receives

• The more different types of species you have (biodiversity) the better an ecosystem can sustain itself

What is the difference between biotic and abiotic?

• Biotic are non-living things
• Abiotic are living organisms
• Biotic is life,
  Abiotic is non-living
• Biotic is non-living, Abiotic is living

A rain forest ecosystem is characterized by high biodiversity and a warm/rainy climate. How might this impact the ecosystem's sustainability if the ecosystem is damaged by a catastrophic event?

• The ecosystem, because it has few plant and animal species, will experience low sustainability, not allowing it to recover

• The ecosystem, because it has many plant and animal species, will experience high sustainability, allowing it to recover

• Biodiversity does not have an impact on an ecosystem's sustainability
