Prairie Review

Adaptations

100

What is an adaptation? a.) A habitat b.) A feature of an organism that helps it survive c.) Where an animal lives d.) An animal that survives in the wild

b.) A feature of an organism that helps it survive

200

Why does a horned lizard spray blood from its eyes? a.) it is being attacked or feels threatened b.) to show that it is happy c.) to mark its territory d.) it wants to find a mate

A.) it is attacked or feels threatened

300

Which adaptation would be most helpful for a predator who hunts at night? A.) a loud voice B.) dark fur or feathers C.) large/powerful eyes D.) horns for defending from attack

C.) large/ powerful eyes Larger eyes help nocturnal predators take in more light and increase the power of their nighttime vision

400

Which is the best example of a camouflage adaptation? A.) sharp, pointy feathers B.) pattern of fur to blend in with grasses C.) large fangs to bite predators D.) long fur to keep in heat

B.) pattern of fur to blend in with grasses Fawns or baby deer are born with spots to help them blend in with grasses and the forest floor

500

Why might an animal adapt to look like a predator? A.) To blend in with its environment B.) To keep other animals away from its food C.) To find a better habitat D.) To stop other animals from trying to eat them

D.) to stop other animals from trying to eat them Example: some butterflies and moths have wing patterns that look like owls' faces when they are fully spread

Producers and Decomposers

100

What is a producer? A.) An organism that gets its energy from eating plants B.) An organism that gets its energy from the sun and photosynthesis C.) An organism that eats other animals D.) An organism that feeds on decaying material

B.) An organism that gets its energy from the sun and photosynthesis

200

What is a decomposer? A.) An organism that breaks down decaying materials into nutrients that are returned to the soil B.) An organism that feeds on other living organisms C.) An organism that can eat both live plants and animals D.) An organism that uses the sun's energy to make food

A.) An organism that breaks down decaying materials into nutrients that are returned to the soil Plants cannot use the nutrients from dead or decaying plants and animals until decomposers break them down.

300

Which of these is a producer? A.) hawk B.) mushroom C.) squirrel D.) green algae

D.) green algae Green algae use sunlight to produce their needed energy. Mushrooms (fungi) are decomposers and can survive without sunlight.

400

Which organism is a decomposer? A.) grasses B.) worm C.) spider D.) snail

B.) worm

500

What kind of organism is bacteria? A.) producer B.) carnivore C.) decomposer D.) herbivore

C.) decomposer

Consumers

100

What are the three types of consumers? A.) herbivores, carnivores and producers B.) herbivores and carnivores C.) producers, carnivores and omnivores D.) carnivores, herbivores, and omnivores

D.) carnivores, herbivores, and omnivores

200

Which of these is a consumer? A.) tree B.) mouse C.) egg D.) sunflower

B.) mouse

300

Which of these is an herbivore? A.) deer B.) badger C.) snake D.) raccoon

A.) Deer are herbivores because they eat ONLY plants and grasses

400

What can be determined about predators who eat only other animals? A.) They are omnivores B.) They hunt at night C.) They are carnivores D.) They are the biggest animals

C.) They are carnivores Carnivores are not always the biggest animals! Bison are large herbivores who graze yet they are prey to animals smaller than themselves.

500

Which animal would most likely compete against other animals to find mice to eat? A.) owl B.) mouse C.) coyote D.) spider

A.) Owls eat mice, so they must compete against other animals who eat mice to find food

Food Chains and Webs

100

What does a food chain always show? A.) Who eats mice B.) Linear sequence showing the transfer of energy from one food form to another C.) A web of connections between animals D.) The way the sun helps all animals make food

B.) Linear sequence showing the transfer of energy from one food form to another

200

What is the best way to explain how a food web is different from a food chain? A.) A food web shows more than one single path of energy transfer B.) A food web has more arrows C.) A food web shows transfer of energy D.) A food web shows who eats who

A.) A food web shows more than one single path of energy transfer Food webs show how multiple plants and animals in an ecosystem are connected. A food web will show all of the animals that eat grasses, mice, etc. instead of just one.

300

What is the correct order from beginning to end of the food chain? A.) Sun, mouse, grasses, owl B.) Owl, sun, mouse, grasses C.) Mouse, grasses, sun, owl D.) Sun, grasses, mouse, owl

D.) Sun, grasses, mouse, owl

400

What is the correct order of energy transfer from beginning to end? A.) sun --> berries --> squirrel --> bacteria B.) berries --> squirrel --> coyote --> sun C.) squirrel --> grasses --> fox --> prairie dog D.) prairie dog --> bacteria --> coyote --> grasses

A.) sun --> berries --> squirrel --> bacteria When Decomposers and Sun are included in a Food Chain: Bacteria or decomposers will always appear at the end of a food chain The sun is always at the beginning of a food chain

500

Which organism is missing from this food chain? SUN --> GRASSES --> ? --> BOBCAT A.) mushroom B.) butterfly C.) frog D.) deer

D.) deer

Miscellaneous

100

Why do prairie grasses have extra long roots? A.) to ensure they can reach water and survive after a prairie fire B.) so that they do not blow away in heavy winds C.) it is a useless adaptation D.) to make sure the plant survives if a prairie animal builds a habitat in them

A.) to ensure they can reach water and survive after a prairie fire

200

How do bison use their horns to help them survive? A.) To help them sense prairie fires B.) To help them find grasses that are covered in snow during winter C.) To help defend themselves and fight for a mate D.) To help keep their heads warm

C.) To help defend themselves and fight for a mate

300

What is an owl pellet? A.) A ball of fur that owls eat B.) A ball of fur, feathers and bones that owls regurgitate after digestion C.) A ball of grasses the owl cannot digest D.) A piece of owl food you buy at the store

B.) A ball of fur, feathers and bones that owls regurgitate after digestion

400

How do producers help other organisms survive? A.) They provide protection and securiry B.) They add color to the prairie C.) They help break down organisms and put their energy back into the soil D.) They use the sun's energy to create nutrients for other organisms

D.) They use the sun's energy to create nutrients for other organisms

500

Why do ecosystems such as prairies benefit from more biodiversity? A.) An abundance of organisms strengthens the stability of the food web B.) More kinds of animals means more kinds of predators C.) Organisms will not have to compete with as many animals for food D.) Biodiversity is good for carnivores and producers only.

A.) An abundance of organisms strengthens the stability of the food web
