Multiple Choice

A food web is:

• Two or more food chains that overlap.

• An organisms that eats other living organisms to get energy.

• The path of food energy in an ecosystem as one living thing eats another.

• An organism that breaks down the remains of dead organisms.

Multiple Choice

Which type of consumer eats meat and plants?

• Herbivores
• Carnivores
• Omnivores
• Plants

Multiple Choice

Which best describes what a food chain shows you?

• Energy flow through an ecosystem
• Food flowing through an ecosystem
• Consumers going into other consumers
• Who eats who

Multiple Choice

Multiple Choice

The roadrunner is a desert bird that eats fruits and seeds. It also eats insects, spiders, scorpions, and rattlesnakes.

What would likely happen if the roadrunner population disappeared from its ecosystem?

• There would be no more fruits or seeds.

• There would a decrease in spider populations.

• The rattlesnake population would stay the same.

• There would be an increase in scorpion populations.

Multiple Choice

The shortgrass prairie is an ecosystem found in the Great Plains. Many different populations of animals depend on the prairie ecosystem for survival. A typical community includes animals such as snakes, birds, mice, rodents, and insects.

Which food chain most accurately demonstrates the flow of energy in a shortgrass prairie ecosystem?

• grasshopper → bird → rodent → buffalo

• hawk → snake → mouse → grasshopper

• grasshopper → mouse → snake → hawk

• snake → hawk → skunk → mouse

Multiple Choice

Multiple Choice

What may happen if the snowshoe hare was removed from the food web pictured?

• The insects in the habitat would increase.
• The shrew population would decrease due to being only hawk food source.
• The willow tree population would decrease.

Multiple Choice

Why is there a limited amount of energy that can be passed on to the next feeding level?

Multiple Choice

An energy pyramid represents what?

• How much sunlight is available for the ecosystem to use.

Multiple Choice

The arrows in a food chain or web represents what?

• They point to the organism that is being eaten.

Multiple Choice

What does a food chain represent?

• How all living organisms within a habitat are connected.
