Question 1

Use the terms in the list to identify each lettered portion of the food web.  
-quaternary consumers

Accepted Answer

B

Question 2

Explain how it is possible that a porcupine can kill a leopard.

Accepted Answer

Porcupines release hairs that are modified into sharp, barbed quills, which, when stuck into a predator, can cause severe pain and swelling. The spines detach easily from the porcupine and damage the leopard's mouth. This damage, combined with infection, can cause death.

Question 3

Discuss one hypothesis that attempts to explain the high species richness in the tropics.

Accepted Answer

The climate in the tropics, which includes warm temperatures and plenty of rainfall throughout the year, promotes a long growing season. This longer growing season increases the availability of fruits and plants throughout the year, which enables many animals to easily survive in that environment. For that reason, tropical forests that grow under milder physical conditions include many thousands of species.
