A builder is proposing a new housing development in an area of western Massachusetts. Construction of the housing development will destroy the wetland habitat in the area.
Which of the following would be the most likely consequence of the wetland’s destruction?

• The wetland plant species would disperse to adjacent meadow habitats.
• The populations of wetland animals would be unable to survive in that area.
• The wetland animal species would survive by interbreeding with non-wetland species
• The populations of wetland plants would evolve to disperse seeds by wind rather than water.

In the 1850s, Thomas Austin released approximately twenty-four rabbits from Europe into the Australian countryside. By 1900, tens of millions of rabbits were found all over the Australian continent. The warm Australian climate, abundant farmland, and crops provided the perfect habitat for the rabbits. The rabbits caused extensive damage to all vegetation, and the lack of plants increased soil erosion. Why were the rabbits so successful? 

• the rabbits competed with local herbivores for food
• the rabbits did not have natural predators
• erosion of soil benefited the rabbits
• diseases helped decrease rabbit populations

Cutting down large forests (deforestation) can result in:

• little to no changes

• more homes for animals

• less plants to absorb carbon dioxide, a greenhouse gas

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.
