An organism that can make its own food.

A consumer that eats only plants.

A consumer that eats both plants and animals.

an organism that breaks down chemicals from waste and dead organisms and returns important materials to the soil and water.

The pattern of overlapping food chains in an ecosystem.

An organism that obtains energy by feeding on other organisms.

A consumer that eats only animals.

A carnivore that feeds on the bodies of dead organisms.

A series of events in which one organism eats another and obtains energy.

A diagram that shows the amount of energy that moves from one feeding level to another in a food web.

What do herbivores and carnivores have in common?

Both herbivores and carnivores feed on other organisms.

What energy role is filled by the first organism in a food chain?

The first organisms in a food chain play the role of producer.

Why is the pyramid shape useful for showing the energy available at each of levels of a food web?

Thw shape shows how available energy decreases at higher levels of a food web.

Name the three energy roles that organisms fill in an ecosystem.

Producers, consumers and decomposers.

How do organisms in each of the three energy roles obtain energy?

Producers use energy, usually sunlight, to make their own food. Consumers eat other organisms. Decomposers break down organisms' wastes and remains.

Why is a food web a more realistic way of portraying an ecosystem than is a food chain?

Because most organisms are part of many overlapping food chains.

How does the amount of energy available at one level of an energy pyramid compare to amount of energy available at the next level up?

The amount of energy available on one level of an energy pyramid is 10 times greater than that available at the next level up.

What does an energy pyramid show?

The amount of energy that moves from one feeding level to another in a food web.

Why are there usually few organisms at the top of an energy pyramid?

Because so much energy is lost from one level to the next level up, the energy available at the top level can support few organisms.
