a

Organisms that live in desert and desert-scrub biomes have developed unique adaptations that aid in their survival. Coyotes are crepuscular desert mammals that grow to be approximately three feet tall and weigh between 20 and 50 pounds when full-grown. How does being crepuscular help enable the coyote to survive the heat of the desert? a. It is only active at dawn and dusk b. It is only active at noon c. It is only active at night d. It is only active in the morning

a

Organisms use different types of adaptations to aid in their survival. Many different types of animals hibernate throughout the winter. During hibernation, the animal's metabolism slows and its core temperature lowers. What is this process called? a. torpor b. sleep c. hyperactivity d. none of the above

a

What are some adaptations of the kangaroo rat that allow it to survive in the desert biome? a. builds underground burrows, hunts at night, obtains water from its food b. builds nests inside trunks of large plants, hunts during daylight hours, obtains water from its food c. builds underground burrows, hunts at night, requires a water source for drinking d. builds exposed nests under brush and scrub, hunts at night, obtains water from its food

a

When growing in windy environments, this organism will grow low along the ground, but when growing in sheltered environments, it grows tall. The leaves have a waxy coating to reduce moisture loss, a chemical makeup that makes them fairly fire resistant, and produce a scent that deters predators. It also has a large root system and root crowns. What organism and environment is described above? a. coyote brush and chaparral b. cacti and desert c. mesquite and savanna d. coyote brush and taiga

a

Which of the following is the classic hot and dry desert? a. arid desert b. coastal desert c. cold desert d. none of the above

a

How is the California quail adapted to live in the chaparral biome? a. tree-dwelling b. crepuscular activity c. nesting in trees d. moisture-rich diet

b

The chaparral biome is best characterized by _______. a. heavy snowfall b. woody scrub plants c. flat terrain d. mountainside terrain

b

Which of the following is not true about arid deserts? a. They can be found in North America. b. The rain falls mostly as snow during the winter. c. They are very hot and dry. d. The rain often evaporates before it hits the ground.

b

Which of the following is not true about the Sahara desert? a. it is almost as large as the United States b. occupies central and southern Africa c. has sand dunes almost 600 feet high d. has a 3 million year history

b

Which of the following would you least likely find living in the chaparral biome? a. ground birds b. pine trees c. olive trees d. aromatic plants

b

Marmots are a type of _______. a. canine b. feline c. squirrel d. nocturnal predator

c

Organisms that live in desert and desert-scrub biomes have developed unique adaptations that aid in their survival. The Sahara Desert takes up ten percent of the continent of Africa, and is the largest desert in the world. The species that live in the Sahara are highly adapted to survive in the extreme conditions they live in. What morphological and physiological adaptations might be seen in the organisms that live in the Sahara Desert? a. water absorbing skin, large eyes for hunting at night, webbed feet b. light colored fur or feathers for camouflage, dense layer of fat and fur for warmth, hibernation during cold months c. small bodies and long limbs in warm-blooded organisms, light colored fur or feathers to reflect sunlight, lack of sweat glands in many organisms, hibernation during hot months d. dark colored fur or feathers for heat absorption, large bodies and short limbs, consumption of primarily scrub and short grasses

c

The heaviest and fastest of all the small wildcats is the _______. a. jaguar b. tiger c. caracal d. bobcat

c

What kind of vegetation would you most likely expect to find in the chaparral biome? a. deciduous trees b. tall grasses c. hardy shrubs d. tall pine trees

c

What type of plant is the creosote bush? a. coniferous tree b. lichen c. shrub d. flowering weed

c

When the Barrel and Saguaro cacti absorb moisture they store it _______. a. in their roots b. in their spines c. in the flesh of their barrels d. in underground root nodules

c

Which of the following deserts is characterized by moderately warm to cool temperatures? a. arid b. semi-arid c. coastal d. cold

c

Jackrabbits' large ears are an adaptation for _______. a. hunting prey b. enhanced hearing c. storing water d. dissipating heat

d

The aromatic oils of chaparral shrubs _______. a. promote wildfires b. make many plants flavorful cooking herbs c. help shrubs eliminate their competitors d. all of the above

d

What abiotic factors describe the desert biome climate? a. four distinct seasons, a temperature range from just below freezing to 70º F, almost 14 inches of rain in the winter months and more than 18 inches of rain in the summer b. warm temperature year round, very long dry winter and a very wet summer, a temperature range of 68° to 86° F, annual precipitation of 10 to 30 inches c. subarctic and cold climate, long, severe winters, average yearly rainfall is 15 to 20 inches d. extremely low humidity, less than 10 inches of rain per year, high temperatures during the day, frequently windy

d

Which of the following best describes daily temperatures in deserts? a. hot during the day and cold at night b. hot during the day and warm at night c. cool during the day and very cold at night d. they depend upon the type of desert and its location

d

Which of the following is not an adaptation of California thrashers to life in the chaparral biome? a. a long, curved beak for scratching at the ground b. nesting in late March c. a preference for walking over flying d. nocturnal activity

d

Which of the following would be particularly damaging to the chaparral biome? a. wildfires b. flooding c. drought d. none of the above

d

All deserts have high daytime temperatures.

f

The chaparral biome is generally characterized by its terrain.

f

Desert plants are often widely spaced due to competition for rainwater.
