Accepted Answer

Keystone species are species that influence the viability of a community

Question 9

Explain the the basis for deciding which species to preserve and what methodology to use)Landscape protection for one species is often beneficial for other wildlife that shares the same space.

Accepted Answer

Protecting the landscaspe for one species has overlap with protection of other species

Question 10

Accepted Answer

Metapopulation is a population inadvertently fragmented by humans into several small,isolated populations.

Question 11

Which of the following statements is false about the impact of biodiversity on biogeochemical cycles?

Accepted Answer

Definition of an alien species

Question 13

Which of the following is not a major cause of extinction today?

Accepted Answer

Habitat loss,alien species,pollution,disease,and over exploitation are the main reasons for the extinction of species today

Question 14

A ________________ lives where the environment is not very favorable and the birthrate equals death rate at best.

Accepted Answer

A sink populations is one in which the environment is not as favorable and where the birthrate equals the death rate at best.

Question 15

Which of the following is primarily due to air pollution from sulfur dioxide and nitrogen oxides?

Accepted Answer

Both sulfur dioxide from power plants and nitrogen oxides in automobile exhaust are converted to acids when they combine with water vapor in the atmosphere.These acids return to Earth as either wet deposition (acid rain or snow)or dry deposition (sulfate and nitrate salts).

Question 16

So far,habitat loss has only occurred in the tropical regions.

Accepted Answer

Locations of habitat losss are all over the world.

Question 17

Which of the following is false about alien species?

Accepted Answer

The truths about alien species,what they really do to a habitat.

Question 18

The introduction of the zebra mussel from the Caspian Sea to the Great Lakes was:

Accepted Answer

Understand problems associated with and caused by introduced species

Question 19

Sustainable development is the removal of a number of individuals so that the population is severely reduced.

Accepted Answer

To achieve a sustainable society,resources such as clean air,water,an adequate amount of food,and living space for humans and wildlife will have to be preserved.This goal is not possible unless we carefully regulate our consumption of these resources today,taking into consideration that the human population is ever increasing.

Question 20

Which of the following statements is false about overexploitation?

Accepted Answer

Overexploitation occurs when too many members of a wild population are taken reducing the number
