Several owls live in a forest. The owls prey on mice. Hawks also prey on mice. Which might happen if several hawks move to the forest where the owls live?

The number of owls and mice will decrease.

The number of owls will increase, and the number of hawks will decrease.

The number of mice will increase, and the number of owls will decrease.

The number of owls and hawks will increase.

A pyramid shape is used to show the amount of available energy at each trophic level because...

energy decreases as you go up the food chain, just like the pyramid shape gets smaller as you go up.

energy increases up the food chain just like the pyramid shape gets smaller as you go up.

energy amounts are the same at each trophic level

If only 10% of an organism's energy is available for the next trophic level, what happens with the other 90% of the energy?

It is used for life processes or lost as body heat.

It is destroyed after it is used up.

It remains for the next trophic level IF the predator consumes ALL of the organism.

It is lost completely as body heat.

Why are producers found at the base of the pyramid?

All of these answers are correct.

They create all of the energy and therefore have the most energy of all of the trophic levels

There are more plants than animals.

They begin the flow of energy in an ecosystem.

True or False: Organisms will always stay in the same trophic level.

False-- the trophic level an organism belongs to is based on what it is consuming in the food chain.

True-- an organism's trophic level is permanent based on the species it is.

The diagram is intended to show relationships in an ecosystem. What do the arrows represent?

The direction of the energy flow

The direction of population migration

Progressively smaller organisms

What does a food web represent?

All connections of energy flow throughout all organisms in a habitat.

The specific ways that mutualism is carried out.

A single pathway or energy flow between organisms.

Why might an organism have more than one arrow coming from them in a food web?

More than one organism may eat them.

They may eat more than one other organism.

This organism gets its energy from multiple sources.

They have no resources available to them.

The populations of which organisms will most likely increase as a result of a disease that suddenly reduced the population of Texas horned lizards?

Grasshoppers and Texas Cottonmouths

Texas cottonmouths and red shouldered hawks
