What is a keystone species?

• A keystone isn't a living thing, it's just a stone

• Keys and stones have nothing to do with ecology

• A species that lives in or around rocks

• A species that helps to hold an ecosystem together

A drought has hit this grassland biome. How will this effect the rabbit population?

• The rabbits will increase in number.
• The rabbit population will stay the same.
• The rabbit population will decrease.
• The rabbit population will become extinct immediately.

Which organisms in the food web shown to the right are predators that compete for the same prey in this environment?

• Coyotes and rabbits
• White-tailed deer and rabbits
• Leafy weeds and cotton rats

Why is it important to conserve the biodiversity of Earth?

• to decrease the amount of global predator populations
