Building Food Chains

What is a food chain?

All the energy in an ecosystem starts with the Sun. A food chain is a way of showing how energy passes from one living thing to the next as they eat and are eaten.

A food chain always begins with a producer — usually a plant, which makes its own food using energy from the Sun. Next come the consumers — animals that cannot make their own food, so they eat other living things to get energy.

Sun Grass producer Rock wallaby consumer Wedge-tailed eagle consumer The arrow points to the living thing doing the eating. You can read each arrow as "gives energy to".
A simple Australian food chain: grass → rock wallaby → wedge-tailed eagle. Energy from the Sun passes along the chain in the direction of the arrows.

Q3. Are humans producers or consumers? Circle your answer and explain how you know.

producer   /   consumer

Q4. Make your own food chain using living things that live together in one Australian habitat. Draw at least three living things and join them with arrows that point the right way. Label the producer and the consumers.

Q5. Explain what your arrows show. Use the words energy and Sun in your answer.
