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

What groups of organisms are most in danger of extinction?

• those with large populations that breed quickly

• those with small populations

• those that migrate or need special habitats

• small populations and special habitat needs

Why are there 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 these answers

It is often difficult to save individual species because

• small populations are more prone to disease

• inbreeding may result in genetic disorders

• captive species may not reproduce in the wild

• all of these answers

Reasons for preserving biodiversity include all of the following except

• isolating unique genetic material so it can be incorporated into existing crops

• increasing the chances of discovering organisms with medicinal value

• preventing natural evolution

• finding new plants that can supplement the world’s food supply
