WORKSHEET 1

1. Match these words with the definitions below. You will use each word once.

PRODUCER / CONSUMER / DECOMPOSER / CARNIVORE / OMNIVORE / HERBIVORE

A(n) ___________________________ is a plant and makes its own food.

A(n) ___________________________ is not a plant and can’t make its own food.

A(n) ___________________________ eats dead plants and animals.

A(n) ___________________________ eats only meat.

A(n) ___________________________ eats only plants.

2. What is a food chain?

______________________________________________________________________________
______________________________________________________________________________
______________________________________________________________________________

3. Draw a picture (using arrows) of a food chain and label it.

4. Food Chain

green plant (producer)

herbivore (consumer)

carnivore (consumer)

omnivore (consumer)

decomposer (consumer)

All living things need energy from food. Green plants are the only living things that can make their own food. For that reason, they are called producers. Animals are consumers because they eat plants or other animals to get their energy. Decomposers are consumers that break down dead plants and animals.

They return materials stored in dead plants and animals to the soil, water, and air. Then green plants use these materials to make food. A food chain always begins with a producer. The first consumer in a food chain is an herbivore (an animal that eats only plants). The next consumer is a carnivore (an animal that eats only other animals). A carnivore may be eaten by a larger carnivore. A food chain sometimes includes a consumer that is an omnivore (an animal that eats both plants and animals).

Answer each riddle below with one of the underlined words. Use each word once.

1. I am a fungus. I bread down dead plants and animals. What am I?_______________

2. I am a tree. I make my own food. What am I?_________________

3. I am a living thing that cannot make food. What am I?___________
4. I am a bear. I eat berries and fish. What am I?________________
5. I am a moose. I eat grass, leaves, and twigs. What am I?_________
6. I am a wolf. I eat mice and rabbits. What am I?________________

WORKSHEET 1:

Using Relative Clauses to Make Definitions

Make a definition of the following words and give an example of each. Please write in sentences. Use a relative clause to make your definition.

Example:

A ____________ is an animal that ____________

WORKSHEET 2:

Food Web

A food web shows how energy is passed on from one living thing to the next. It shows the feeding habits of different animals that live together in an ecosystem.

Producers are living things that make their own food with sun and air. The producers are pictured at the bottom of the food web.

Consumers are living things that eat other living things.

Use the food web in the picture above to answer the questions.

1. Name the living things in the food web that are producers. _________________________

2. Name the living things in the food web that are consumers. _________________________

_______________________________________________________________________

3. Which living things does the snake eat? _______________________________________

4. Which living things does the fox eat? _________________________________________

5. What is eaten by the rabbit? ______________________________________________________

WORKSHEET 3:

Producers and Consumers

A producer is a living thing that makes its own food from sunlight, air, and soil. Green plants are producers who make food in their leaves.

A consumer is a living thing that cannot make its own food. Consumers get their energy by eating food. All animals are consumers.

A decomposer is a living thing that gets energy by breaking down dead plants and animals. Fungi and bacteria are the most common decomposers.

Tell whether each living thing below is a producer, consumer, or decomposer.

a. apple tree - _____________________ b. hawk - ______________________

c. mushroom -_____________________ d. carrot - _____________________
