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
Where are some of the unique ecosystems of the United States?
Pacific Northwest
California
Florida Everglades
Hawaii
All of the locations listed
How did the CITES treaty reduce the slaughter of elephants?
It placed all the elephants in city zoos to keep them safe
It banned imports and exports of all ivory worldwide
It limited sales of ivory to the antique market
all of these answers
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
Where are many critical biodiversity hotspots located?
cities and developed areas of the world
islands, tropical rain forests, and coastal areas
desert and polar environments
all of these
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
What human activities have influenced recent extinction events?
habitat destruction
poaching
introducing exotic species
all of these
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
