It is estimated that half of the 10 million species of organisms on the planet live in the tropical rain forests. Deforestation of the rain forest causes the extinction of as many as 50,000 species per year. Clearing tropical rain forests causes the extinction of many species because

• plants and animals are exposed to high levels of carbon dioxide.

• pollution caused by humans increases the greenhouse effect.

• many unique habitats and ecosystems are being completely destroyed.

• destruction of the rainforest contributes to the depletion of the ozone.

In the forest spotted owl make their home in the cavities of dead trees. The same habitat is home to rodents that owls feed on. Logging by humans have caused the population of owls to decline. What statement BEST explains the relationship between humans and the spotted owl.

• humans have taken away resources needed by owls, so there are fewer owls.

• Humans increased the available food for the owls, so there are more owls.

• Humans eliminated predators of the owls, so the owls increased.

• Humans moved the owls to the zoo, so there are less owls in the woods.
