What is a consumer?
An organism that gets energy by eating plants or other animals.
What is a decomposer?

What is a food chain?
path that shows how energy passes from one organism to another.
A fish lives in a pond. What is its habitat?
The pond.
Is grass a producer or a consumer?
A producer.
Is a rabbit a producer or a consumer?
A consumer.
Name one example of a decomposer.
A mushroom or bacteria.
What is the main source of energy for most food chains?
The Sun.

A deer, rabbit, fox, or squirrel.
What does a plant use from the Sun to help it make food?
Sunlight (energy).
What do you call an animal that hunts and eats another animal?
A predator.
What happens to a dead leaf when decomposers break it down?
It breaks down and returns nutrients to the soil.
In this food chain, grass → rabbit → fox, which organism is the producer?
Grass, because it makes its own food.
What might happen to rabbits if their habitat no longer provides enough food or shelter?
They may move to another habitat or have difficulty surviving.
Name one producer that lives in an aquatic ecosystem.
Algae or an aquatic plant.
In the food chain grass → grasshopper → frog, which organism is the consumer that eats the grasshopper?
The frog.
an decomposers be found in both aquatic and terrestrial ecosystems?
Yes. They live in water and on land.
In the food chain Sun → grass → grasshopper → frog, what does the arrow show
The direction energy moves from one part of the food chain to the next.
What is a habitat?
A place where an organism lives.
In this food chain, Sun → grass → rabbit, which organism is the producer, and why?
Grass, because it makes its own food using sunlight.
In the food chain Sun → plant → mouse → snake, what would happen to the snake population if there were no more mice?
The snake population might decrease because snakes would have less food.
Why are decomposers important to an ecosystem?
They break down dead organisms and return nutrients to the environment so they can be used again.
