TO EXPLAIN WHAT PRODUCERS,

CONSUMERS AND PREDATORS ARE

Food Chain

1. Food relationship among organisms in an ecosystem, every plant and animal is called a link.

2. Energy is consumed and transferred.

3. All energy comes from the sun.

4. Food producers

• Green plants which make food to provide for the rest of the organisms in the food chain.

5. Consumers

• Animals that eat plants and other animals.

   a) Primary consumer – herbivore feeding directly on plants.

   b) Secondary consumer (predator) – carnivore feeding on primary consumers.

   c) Tertiary consumer (predator) – carnivore feeding on secondary consumers.

6. Since energy is lost along a food chain, most or all the energy would have been lost by the time the food chain reaches its fourth or fifth line.
