American Black Bears are omnivorous mammals with a widespread distribution in the forested regions of the United States and Canada.

American Black Bear
Ursus americanus

Which adaptation of black bears best helps them survive long, cold winters?

a.	having a large home range	c.	being able to hibernate
b.	having sharp teeth and claws	d.	eating both plants and animals

An area that is occupied by one animal or a group of animals that do not allow other members of the same species to enter is called a territory. This is an example of a behavioral adaptation.
Which of the following best describes the advantage of this behavior?

a.	Establishing a territory makes it harder for an animal to find a mate.
b.	Establishing a territory is not a survival behavior.
c.	Establishing a territory makes it easier for an animal to raise young and find food.
d.	Establishing a territory decreases the genetic variation of a population.

A muskox is a large, heavy mammal. It has short legs and is covered in long, thick hair.

A muskox is shown in the picture below.

Based on its characteristics, in which environment is a population of muskox best suited to live?

wetland

tundra

desert

rain forest

The Arctic environment has temperatures that range between - 22 C and 6C with lots of snow and ice.
Which adaptation would most likely help a population of organisms survive this environment?

a.	Green feathers and webbed feet	c.	large shell and leathery skin
b.	light colored fur and layers of blubber	d.	long necks and tall legs

Animals have developed structural adaptations that enable them to survive in specific environments.

Structural Adaptation Gills	Structural Adaptation Hooves	Structural Adaptation Moist Skin	Structural Adaptation Thick Fur

Which population would best be adapted to maneuver in a rocky, mountainous region?

a.	a population of organisms with moist skin
b.	a population of organisms with gills
c.	a population of organisms with thick fur
d.	a population of organisms with hooves

Structural adaptations such as sharp teeth, gills, hooves, or wings help organisms survive in various environments.
Which of the choices shown below IS NOT an example of a structural adaptation?

a.	The harmless syrphid fly resembles the yellow jacket in coloring and body shape.
b.	Mole-rats have very large teeth and claws for digging tunnels to escape predators.
c.	The leaf frog’s coloring and shape camouflage it on the forest floor.
d.	A lizard finds a shady spot to escape the sun’s heat during midday.

Geneticists estimate that Polar Bears evolved from Brown Bears about 350, 000 years ago. Polar Bears evolved special adaptations that enable them to survive and hunt in the extreme cold of the Arctic Circle.

Polar Bears

Identify one structural adaptation that polar bears exhibit.

a.	Their fur is light colored which allows them to be camouflaged from their prey.
b.	They have black colored fur which helps them blend into the dark nights when they hunt.
c.	Polar Bears sometimes swim from ice berg to ice berg as they hunt in the Arctic Circle.
d.	Polar Bears will wait outside ice holes to attack seals when they come up for air.

Over time species adapt their behavior and/or their body structures to survive in specific environments.

Structural Adaptation Wings	Structural Adaptation Antlers	Structural Adaptation Gills	Structural Adaptation Six Legs

Which population listed below is best adapted to thrive in an aquatic environment?

a.	a population of organisms with antlers	c.	a population of organisms with gills
b.	a population of organisms with six legs	d.	a population of organisms with wings

The fish shown in the pictures below is the Anglerfish. The stalk in front of its eyes is a flashing light that it uses to lure prey to its mouth. This structural adaptation enables the anglerfish to survive in a very dark and deep aquatic habitat.

Picture A	Picture B

Where are anglerfish likely to be found?

a.	A shallow freshwater lake
b.	The deep abyssal zone of the ocean
c.	In the shallow water of a creek or stream
d.	An estuary or wetland area on the coast.

10.

The Curlew is a bird with a long beak that lives in estuaries along the coast of California.

Which of the following adaptations is most likely the reason that this bird survives in this ecosystem?

a.	The beak attracts more mates.
b.	The long beak keeps the bird’s head dry when it is raining.
c.	The beak allows the bird to fly into the taller trees near the estuary.
d.	The long beak enables the bird to reach food buried in the mud.
