Biology Chapter 5

In which location would you expect to find the greatest species diversity?

Costa Rica

Approximately how much greater is the current background extinction compared to the normal rate?

1000 times

biological augmentation

A method that is used to restore bio diversity to a polluted or damaged area

How is a bridge over the road and advantage of a habitat Corridor?

members of species can move safely from one area to another

Why is there more species diversity in southern Florida then there is the northern Alaska?

the milder climate in Florida supports a wider range of habitats or animals

ecosystem diversity

the variety of ecosystems that are present in the biosphere

How can eutrophication be reduced in waterways?

to reduce the run off of fertilizers, Animal waste, and sewage into waterways

Extinction

Occurs when the last member of a species dies

What does Wilson mean when he says, "this is the folly our descendants are least likely to forgive us"?

Our children and grandchildren will wonder why we did not take steps with in the loss of biodiversity

What condition triggered the chain of events off the coast of Alaska that caused the kelp forests to begin to disappear?

Over the harvesting of plankton - eating whales

Why do reserves protect biodiversity?

Sustainable use of natural resources means they will be used at a rate at which they can be replenished recycled

Why would Wilson compare the loss of biodiversity with energy depletion, economic collapse, nuclear war, and conquest?

The catastrophic events can affect anyone and everyone

Why is it not a good idea to release exotic pets into a local ecosystem?

The exotic pet would be in introduced species that can exploit ecosystem at the expense of native species.

species diversity

The number and relative abundance of species in a biological community.

Why does two different colored rabbits help a species survive?

The variety of colors allows the rabbit species to survive in different types of environments.

Why are the rhinos in danger of becoming extinct?

They are hunted and killed for their forms which are used in Asian markets for medical purposes

Which is not a way in which species lose their habitat? Background extinction, distraction, just ruction, or pollution?

Background extinction

the name of the process of using living organisms to detoxify a location

Bioremediation

Why does increased ecosystem diverse city contribute to increase the biodiversity in the biosphere?

Each ecosystem supports a different variety of life

What are three values that the biosphere provides?

Economic, aesthetic, and scientific values

Forest, freshwater ale, estuary, and prairie Are examples of what?

Ecosystem diversity

What are species called that are found in only one geographic location?

Endemic

How would an environmental microbiologist use bioremediation to detoxify polluted areas?

Increased population numbers and standards of living will put additional strain on renewable sources, as a result more more people will have to cut their sustainable use.

Clothes represent an indirect or direct economic value of biodiversity?

Indirect

How was biodiversity change since the 1980s?

It has been decreasing

What are renewable resources?

Resources that are Replaced by natural processes faster than they are consumed

Nonrenewable resources

Resources that are found in limited amounts or replaced by natural processes of extremely long periods of time.

Why is it difficult to attach a value to the aesthetic qualities of biodiversity?

What one person considers desirable my not be viewed in the same way by another person.
