Biodiversity, aka biological diversity, usually refers to

the number of different species in a given area

the number of animal species in a given area

the number of plant species in a given area

High biodiversity is

having a lot of the same organism.

having a few of the same organism.

having a lot of variety of different organisms.

only having one of each organism.

Biodiversity is the variety of ________ in a community.

genes

population

species

community

A community is

Several different populations scattered across several states.

Several different organisms in the same geographic area

One type of organism in the same geographic area

Several different populations in the same geographic area

A population is

a group of similar species in different areas

a group of the same species in the same geographic area.

a group of several species in the same geographic area

a group of several species along with their abiotic factors in a small area.

A species that is likely to become extinct if protective measures are not taken immediately is known as

threatened species

endemic species

keystone species

endangered species

An exotic species is

a species that is not native to a particular region

a newly discovered species in a particular region

a genetically modified species in a particular region

a species that is native to a particular region

An endemic species is

exotic and found everywhere

exotic and found only in certain regions

native and found only in a limited area

native and found everywhere

a species that is not native to a particular region and has no natural predators and little competition

consumer species

producer species

invasive species

adapted species

10.

Why are invasive species such a problem in their new ecosystem?

c. We are destroying the habitats of a large number of species

d. Recreational hunting

19.

The lionfish is a venomous fish found primarily in the Red Sea and the Indian Ocean. In the 1990s, lionfish were accidentally released into the Atlantic Ocean, where they found abundant resources and favorable environmental conditions. Which of the following scenarios is most likely to result in the lionfish having a major impact on the communities into which they were introduced?

With no natural predators, the lionfish population will become very large.

Some native species of invertebrates will develop a resistance to lionfish venom.

Random mating will allow the lionfish population to reach Hardy-Weinberg equilibrium.

A virus that specifically infects lionfish will become more prevalent.

20.

Which of the following describes the importance of biodiversity to an ecosystem?

a. People like to be able to see all the different plants and animals

b. If there aren�t all the different species, there will be resources that aren�t being used
