This picture is a very good example of a food chain.
A rabbit eats a carrot, then the fox eats the rabbit, finally the lion eats the fox. And maybe a dinosaur eats the lion.

Slide 3
Oh! What's a food web?
A food web is made up from many different food chains. They are all interdependent.
What is a producer and what is a consumer?
Producers are plants, they produce food by photosynthesis.
consumers are animals, they consume food for energy.
The organism who consumes producers is called primary consumer.
The organism who eats the primary producer is a secondary consumer.
In this picture, rabbit will be the primary consumer and the fox will be the secondary consumer.
