Chapter 5 Biodiversity, Conservation(VCA)

The major threat to biodiversity is:

• habitat fragmentation

• habitat loss

• habitat degradation

• exotic species

The major focus of conservation biology is

• prevent cruelty to animals

• to keep animals in zoos for people to see

• protect species from extinction

• stop hunting

Acid rain changes the pH of soil, killing some trees. This is an example of :

• habitat fragmentaion

• global warming problems

• habitat degradation

• exotic species

For many years orchid collectors searched Exotic Islands for the beautiful Kimmarie Orchid, which is found no place else in the world. After they found the orchid, they brought it back to their homes. In the last couple of years the Kimmarie Orchid has not been found on the island. As a result, hobbyists are now sending the Kimmarie Orchid to be replanted on the island.

The Kimmarie Orchid became extinct in the wild due to:

• habitat loss

• exotics

• habitat degradation

• overcollection

The hobbyists are trying to correct the Kimmarie Orchid problem they caused by using:

• exotic species

• a reintroduction program

• habitat corridors

• habitat fragments

Carnivorous birds that fed on organisms exposed to this chemical produced fragile eggs. The chemical is:

• CFC

• DNA

• DDT

• nitrogen oxide

Salvinia molesta, a floating aquatic plant , first entered Lake Naivasha in Kenya when a person's fish ponds flooded. The plant quickly grew, changing the habitat of parts of the lake. This is an example of a problem do to:

• reintroduction programs

• exotic species

• habitat fragmentation

• edge effect

Which is NOT true of the US Endangered Species Act?

• It was responsible for the creation of Yellowstone National Park

• President Nixon signed it into law in 1973

• It was partially responsible for the recovery of some threatened species

• other countries have created similar laws

A conservation biology organization wants to raise money to buy a strip of land to connect Protected Area A to Natural Park Area B. This strip would most likely serve:

• as a road for tourists

• as a wildlife corridor

• to fragment the havitat

• to slow ozone destruction

Which of the following species is extinct?

• American Bald Eagle

• bison

• passenger pigeon

• giant panda
