In this food chain, what will happen if the frogs become extinct?

The grasshoppers will increase.

The grasshoppers will decrease.

The eagles will remain the same.

The arrows in a food chain or web represents what?

They show what direction the energy is flowing between organisms.

They point to the organism that is being eaten.

They represent how water is transferred within a habitat.

Which scenario describes a population?

a log providing shelter for beetles, spiders, and snakes

all of the sunfish, bass, and catfish living in a lake

Deer and wolves share the same habitat. If the deer population decreased due to being hunted by man, how would this affect the wolf population?

The wolf population would decrease.

More wolves would immigrate to the area.

The wolf population would increase.

The would population would experience no change.

Why are there fewer organisms in each level as you go up the energy pyramid?

There is less energy availabe at higher levels.

There is more energy available at higher levels.

Higher levels have more mean animals.

If a disease killed all the mice in the food web shown here, how would that affect the owls and hawks?

Owls would be affected more because they are predators for fewer animals that the hawks.

Hawks would be affected more because they are predators for more animals than the owls.

Since they are both predators of mice, the hawks and the owls would be affected the same.

Since they are both predators of other animals, neither the hawks nor the owls would be affected.

An increase in population-

causes an increase in the need for natural resources.

causes a decrease in the need for natural resources.
