Non-fiction: The Food Chain
The Food Chain
In order to understand the food chain, there are some vocabulary words
you should learn. Look at the words and definitions below.
Producers – Organisms that make their own food. For example: grass
Consumers – Animals that eat other animals or producers.
Herbivores – Animals that eat only plants, no meat. For example: zebras
Carnivores – Animals that usually eat meat. For example: lions
Decomposers – Organisms that break down deceased animals into tiny pieces
that can be used by producers. For example: earthworms
All food chains begin with a producer. A producer is usually a type of
plant. That producer is then eaten by a consumer. There are usually two types
of consumers, primary1 and secondary2. Herbivores are primary consumers.
They eat plants. Carnivores, secondary consumers, often eat primary
consumers. For example: a zebra (a primary consumer) eats grass (a producer).
A lion (a secondary consumer) eats the zebra.
When an animal or a plant dies, decomposers break down the animal or
plant, returning nutrients back into the environment. These nutrients then feed
the producers, which completes the cycle.
