species

genetic

ecosystem

individual

Multiple Select

Select all the correct answers.

Which are examples of ecosystem diversity?

variety of traits found in domestic dogs

a forest

a variety of birds in a garden

a grassland

an arid desert

Multiple Choice

Which biome is more likely to survive a change in the environment?

High (rich) biodiversity

Low (poor) biodiversity

Multiple Choice

species that are native to and found only within a limited area

endemic

exotic

endangered

extinct

Multiple Choice

a species that is not native to a particular region

endemic

exotic

endangered

extinct

Multiple Choice

Which habitat exhibits the greatest biodiversity?

A habitat with 15 different species with about 300 individuals each

A habitat with 10 different species with about 75 individuals each

Multiple Choice

Why are migratory species harder to protect?

They don’t stay in one place long enough to be counted.

The specific habitats along and at each end of their migration routes must be protected.

There are too many to count.

They migrate from one country to another.

Multiple Choice

Some species are so important to the functioning of an ecosystem that they are called

keystone species

cornerstone species

essential species

exotic species

Multiple Choice

Biodiversity ________ are regions with unusually large numbers of unique ________.

hot spots ; species

species ; hot spots

biomes ; plants

sanctuaries ; flora

Multiple Choice

Which area would have less biodiversity?

desert

forest

ocean

lake

Multiple Choice

Where are many biodiversity hotspots located?

deserts

tropical rain forests

polar ice regions

rocks

Multiple Choice

How can humans best help an endangered species avoid extinction?

they can feed the animals

they can put the animals in a zoo

they can protect the animal’s habitat

they can take the animal to new habitats

Multiple Choice

What is THE most major cause of extinction today?

habitat destruction by humans

poaching

disease

hunting

Multiple Choice

Match each threat to biodiversity to its possible result.

Climate change

cutting down trees in tropical forest

collection of industrial waste in water bodies

gradual increase in global temperature

extinction of specific species that serve as food

Multiple Choice

Match each threat to biodiversity to its possible result.

Pollution

cutting down trees in tropical forest

collection of industrial waste in water bodies

gradual increase in global temperature

extinction of specific species that serve as food

Multiple Choice

Match each threat to biodiversity to its possible result.

Overexploitation of resources

cutting down trees in tropical forest

collection of industrial waste in water bodies

gradual increase in global temperature

extinction of specific species that serve as food

Multiple Choice

Match each threat to biodiversity to its possible result.

Habitat loss

cutting down trees in tropical forest

collection of industrial waste in water bodies

gradual increase in global temperature

extinction of specific species that serve as food

Multiple Choice

This is the extinction of a species one by one, not a sudden loss of many species

background extinction

mass extinction

fragmentation

biotic potential

Multiple Choice

What is the practice of harvesting or hunting to such a degree that remaining individuals may not be able to replenish the population called?

pollution

deforestation

overexploitation

acid rain

Multiple Choice

The primary causes of extinction (and endangerment and threatened status) is...

polar ice cap melting

global warming

habitat loss and degradation

burning of fossil fuels

Multiple Choice

How does habitat fragmentation reduce genetic diversity in species?

Habitat fragmentation makes nonnative species introduction possible.

Habitat fragmentation opens migration routes.

Habitat fragmentation isolates a large population into smaller groups.

Habitat fragementation encourages open gene flow.

Multiple Choice

Habitat loss is a big threat to biodiversity, because as habitat size decreases, the number of species

increases

decreases

stays the same

Multiple Choice

Climate change, due in part to burning fossil fuels, results in which of the following?

ocean acidification that can dissolve shells

increased surface and ocean temperatures

sea level rise

melting glaciers and ice sheets

all of these

Multiple Choice

What is the practice of harvesting or hunting to such a degree that remaining individuals may not be able to replenish the population called?

pollution

deforestation

overexploitation

acid rain

Multiple Choice

the breaking of habitats into smaller pieces is called...

habitat division

habitat pollution

habitat corruption

habitat fragmentation

Multiple Choice

The number of different species and the abundance of each species in a biological community.

genetic diversity

ecosystem diversity

extinction

species diversity

Multiple Choice

What is the variety of genes present?

bidiversity

species diversity

extinction

genetic diversity

Multiple Choice

The loss of habitat

pollution

poaching

habitat fragmentation

habitat destruction

Multiple Choice

How does habitat fragmentation reduce genetic diversity in species?

Habitat fragmentation makes nonnative species introduction possible.

Habitat fragmentation opens migration routes.

Habitat fragmentation isolates a large population into smaller groups.

Habitat fragementation encourages open gene flow.

Multiple Choice

The primary causes of extinction (and endangerment and threatened status) is...

polar ice cap melting

global warming

habitat loss and degradation

burning of fossil fuels

Multiple Choice

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.

all of the above

Multiple Choice

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.

Multiple Choice

Why do the populations of invasive species grow so quickly?

Invasive Species are native to an area.

Invasive species are prey to many animals.

Invasive species have no predators.

Invasive species keep the ecosystems in equilibrium.

Multiple Choice

1. What makes a species invasive?

Moving to a new ecosystem and taking resources from natives

Not having papers

Species that can't adapt

Plants that take up too much space
