Ticks are animals that attach themselves to mammals and birds. They get the energy they need to live by sucking blood from the animals to which they are attached.

Which of the following best explains the role that ticks play in the ecosystem?

• They are host animals because they serve other animals.

• They are producers because they produce baby ticks.

• They are parasites because they live on a live host animal.

• They are prey animals because they attach to predators.

Fleas are small, flightless insects. They have very strong legs and can jump great distances. They live most of their lives on mammals and birds, consuming the blood of their hosts. Fleas can carry a variety of diseases that they can pass to their hosts by directly infecting the blood of the host animal during feeding.

What​ is the best​ explanation​ for why the flea is classified as a parasite?

• The flea spends most of its life living on a host mammal or bird.

• Both the flea and the host benefit from the presence of the flea.

• Fleas are small, flightless insects and can jump from host to host.

• Fleas consume the host’s blood and can transmit diseases to the host.

A population of grasshoppers lived in a large grassy area. Frogs fed on the grasshoppers in the area. During a hot dry summer, much of the grass died.

Which of the claims below is best supported by the evidence?

• The number of frogs would decrease because the number of grasshoppers would decrease.

• The number of grasshoppers would increase because the number of frogs would decrease.

• The number of grasshoppers would decrease because the number of frogs would increase.

• The number of frogs would increase because the number of grasshoppers would increase.

This is a picture of an ecosystem.

What type of community would we most likely expect in this ecosystem?

• alligators, crawfish, cypress trees, ducks, frogs, mosquitoes, water snakes

• bats, cacti, coyotes, rattlesnakes, spiny lizards, jack rabbits

• bison, coyotes, deer, hawks, mice, rabbits, shrubs, prairie dogs

• beaver, black bear, cardinals, deer, pine trees, shrubs, squirrel

Use the following information to answer this question.

Sponge mushrooms are found on the ground where there is an abundance of dead plant matter. Like all forest fungi, sponge mushrooms break down decaying plant matter, recycling important nutrients back into the forest floor.

Based on how it obtains its energy, the​ sponge mushroom would be classified as a

• consumer

• decomposer

• host.

• producer.
