What does biodiversity mean?

The different amount of species in an area

An endangered species is

One whose numbers are so small that it is at risk of extinction

One whose not been spotted after many years.

One whose numbers are abundant.

A species is defined as endangered when it

suffers from damage to its habitat.

suffers from disease or predation.

when there are hazards to the continued life of the species.

What are vulnerable or candidate species?

not in immediate danger but could be soon

species that are no longer endangered

species that have already become extinct with no hope of coming back

What does it mean when an animal is extinct?

Something once lived but no longer exists.

Animals that is at risk of extinction.

Place that protects animals at risk.

What is a conservation program?

Place that protects animals at risk.

Something once lived but no longer exists.

Animals that is at risk of extinction.

Why does species become endangered?

Because their environment changed.

Because they go to another place.

Because new habitats are build.

The US act to prevent extinction, recover imperiled plants and animals , and protect the ecosystems on which they depend upon is called...

The Endangered Species Act of 1973

The Fossil Fuel Burning Act of 2000

Which is NOT a way to save individual species

Preservation of genetic material

Which is NOT a way to save individual species

Selling endangered species for pets

Create laws to protect endangered species

What are some ways species are NOT prone to extinction

Species that need large areas to live or special habitats

Species that are exploited by humans

Why do the populations of invasive species grow so quickly?

Invasive species have no predators.

Invasive Species are native to an area.

Invasive species are prey to many animals.

Invasive species keep the ecosystems in equilibrium.

How can the introduction of an invasive species affect genetic diversity?

It can decrease genetic diversity by outcompeting native species for resources

It can increase genetic diversity by introducing new genes

It generally has no effect on genetic diversity

It can ensure the genetic purity of native species

Based on the table, native organisms will be negatively affected by competition with lionfish if they-

are longer than 45 centimeters.

How does deforestation directly affect biodiversity?

By reducing habitat for many species

By increasing the amount of land available for agriculture

By increasing carbon dioxide absorption

By promoting the growth of new species
