Biodiversity

The current rate of species extinction is

• slower than at any other time in this century

• attributed to the actions of humans

• the result of natural environmental processes

• of little consequence to Earth's long-term survival

The fact that organisms are adapted to survive in particular environments helps to explain why

• captive-breeding programs are often ineffective

• non-native plant species never flourish in new areas

• habitat destruction accounts for most extinctions

• compromise is impossible on environmental issues

What groups of organisms are most in danger of extinction?

• those with small populations

• those that migrate or need special habitats

• those with large populations that breed quickly

• both a and b

The major human causes of extinction today are

• hunting and destroying habitats

• polluting and introducing non-native species

• both a and b

• neither a nor b

Why are so many species still unknown to modern science?

• many of these species are found in remote environments

• smaller species receive less attention than large organisms

• cataloging these species is a huge task

• all of the above

Preserving entire ecosystems rather than individual species is a good conservation strategy because

• only endangered species will be saved

• developers will have greater access to land

• more than one species can be saved

• it will not be necessary for environmentalists to study the ecosystem
