An organism that breaks down dead plants and

animals into nutrients for the soil.

What is a decomposer?

An organism that gets energy by eating both

plants and animals.

What is an omnivore?

An environment that has living and nonliving things

that interact.

What is an ecosystem?

The specific role or job an organism has in its

habitat.

What is a niche?

All the members of one species that live within an

area of an ecosystem.

What is a population?

The different populations that interact with each other in the same area.

What is a community?

A specific body part that helps an organism survive

in its habitat.

What is an adaptation?

A group of different parts that work together to perform a function.

What is a system?

The main source of energy in any ecosystem.

What is the sun?

How many directions a food chain can flow.

What is 1 direction?

These organisms produce their own food from

energy they received from the sun.

What are producers?

These organisms must consume energy from

other organisms.

What are consumers?

These are 2 items that decomposers help put

back into the soil.

What are nutrients and minerals?

This diagram shows how food chains in an

ecosystem are connected.

What is a food web?

This is the kind of temperature in which

decay occurs the fastest.

What is hot/warm?

Two factors that speed up the decaying process.

What are:warmer temperature/

moisture/oxygen

A gas that is released into the atmosphere during the

decay process.

What is carbon dioxide?

The result of an ecosystem that has no

decomposers.

What are too many dead organisms!

A reason why a grasshopper population may decrease in the ecosystem below.

Possible answers:The grass dies and they have no food.The snakes overpopulate and eat them

all.The kookaburras overpopulate and eat

them all.

Explain what would happen if the snake

population disappeared in this ecosystem.

Possible answers:

The eagle would eat more kookaburras and the kookaburras would decrease in population.

The grasshoppers and mice could overpopulate.

Name one food chain that is a part of this food web.

Possible answers:--Sun-orchid-mosquito-frog-raccoon-alligator--Sun-bladderwort-turtle-alligator--Sun-orchid-mosquito-carp-heron-alligator

Explain the difference between a producer and a consumer in this ecosystem.

Producers produce their own food with energy gained from the sun.

Consumers get energy by consuming other organisms.

Put the following steps in order to tell how a decomposer affects an ecosystem:

_____ Finally, animals eat the plants._____ Next, minerals and nutrients are put back into the soil._____ First, decomposers digest the waste and the remains of dead animals._____ Then living plants use the nutrients

First, decomposers digest the waste and the remains of dead animals.

Next, minerals and nutrients are put back into the soil.

Then living plants use the nutrients.

Finally, animals eat the plants.

Final Jeopardy Answer

This is the difference between an animal’s niche and its habitat.

An animal’s niche is its specific role or job in an ecosystem.

An animal’s habitat is simply Slide 2where it lives.
