Producers & Energy
Consumers & Flow
Decomposers & Cycles
Ecosystems Balance
100

The process by which plants use sunlight, water, and carbon dioxide to create food.

Photosynthesis

100

An organism that obtains energy by eating other living organisms.

Consumer

100

Organisms like bacteria and fungi that break down dead material and return nutrients to the soil.

Decomposers

100

An interconnected network of multiple overlapping food chains in an ecosystem.

Food Web

200

The primary source of energy for almost all food webs and ecosystems on Earth.

Sun

200

An animal that eats only plants to survive.

Herbivore

200

The nutrient-rich material created when organic matter is broken down by decomposers.  

Compost

200
Why do humans need plants?

They provide oxygen.

300
What starts all food chains/webs?

Producers

300

An animal that hunts and eats other animals for food.

Carnivore

300

Whey does an ecosystem need decomposers?

To break down the dead stuff.  Otherwise it would all pile up.

300

What could happen if a species is removed from an ecosystem?

The ecosystem could become unbalanced and other food chains could be impacted.

400

An organism that can make its own food using energy from the environment.

Producers

400

A diagram that shows how energy flows from one organism to another.

Food Chain

400
Name examples of decomposers.

Examples:  Fungi, Bacteria, Earthworms, Mushrooms.

400

Explain the energy flow in an ecosystem.  (Where does it start and go?)

Energy flows through an ecosystem from the sun to producers, then to consumers and decomposers, while matter (like carbon and water) cycles continuously.
