Food Chains Lesson

Food Chains

What will we be learning today?

1. Define the term Food Chain.

2. Distinguish between the three types of consumers

3. Construct a food chain

What is a Food Chain?

A food chain is a series of eating interactions between organisms.
All food chains must begin with a producer also called an autotroph.
Arrows indicate who eats who and the flow of energy. Energy decreases along the food chain.

Multiple Choice
