Animal Adaptations

• Plants have a difficult time growing without organic material.

Now What was That?

• What kind of climate does the desert have?

• What animals live there?

• How can animals live there?

• What is the soil like?

Beyond the Desert, Tropical Savannahs

Beyond the Desert

Pride Rock
