A Food Chain is a model that shows how matter cycles and how energy flows through an ecosystem

A Food Chain is a model that shows how matter cycles and how energy flows through an ecosystem

Start with 1. Fungus/Bacteria/Worm, 2. Plants, 3. Grasshopper, 4. Mouse, 5. and Coyote.

Put the other organisms back into the cup.

Arrange the organisms on your white board so that the organism doing the eating is above its source of energy. For example

Draw an arrow pointing in the direction the energy flows and the matter cycles (towards the animal that does the eating)

Some organisms do not eat to get their energy An Autotroph, also called a Producer, is an organism

that gets its energy from the sun Label the organism you think is an Autotroph Draw the sun. Draw an arrow to show which organisms are autotrophs,

and thus get their energy from the sun

Decomposers are organisms that break down (decompose) other organisms that have died. Typically, decomposers are shown at the bottom of the

food chain Label these Organisms Decomposers

Decomposers return dead matter and energy to the

soil for future use by Autotrophs.

Draw arrows pointing to Decomposers to show the source of their energy and matter.

A Heterotroph, also called a Consumer, is an organism that gets its energy and matter from eating other organisms. Label these organisms as Heterotrophs

1st Order Heterotrophs EAT Autotrophs Label these organisms

2nd Order Heterotrophs EAT 1st Order Heterotrophs Label these organisms

3rd Order Heterotrophs EAT 2nd Order Heterotrophs Label these organisms

Draw and label your entire food chain on paper.

arrows go FROM the Matter and Energy Source

TO the organism that uses the Energy and Matter

Write this on the same sheet of paper that has your food chain diagram.

A Food Web is bunch of connected Food Chains

Now use all of the other organisms left and construct a Food Web

Draw and label your food web on paper.
