What groups of organisms are most in danger of extinction?
(a) those with small populations
(b)those that migrate or need special habitats
(c) those with large populations that breed quickly
both (a) and (b)
What human activities have influenced recent extinction events?
habitat destruction
poaching
introducing exotic species
all are correct
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.
How many species are estimated to be living on Earth?
between 10,000 and 1,000,000
between 500,000 and 1 million
between 1 and 5 million
between 10 and 20 million
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 are correct
Where are many critical biodiversity hotspots located?
cities and developed areas of the world
islands, tropical rainforests, and coastal areas
desert and polar environments
all are correct
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 are correct
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?
in Pacific Northwest and California
in the Florida Everglades and Hawaii
both of these are correct
none of these are correct
How did the CITES treaty reduce the slaughter of elephants?
(a) It offered a bounty to tribal leaders for identifying poachers.
(b) It banned imports and exports of all ivory worldwide.
(c) It limited sales of ivory ro the antique market.
both (a) and (c)
