Writing food chains

Here is a diagram of the feeding relationship in the story.

Feeding relationship in the jungle

This diagram isn't complete because it does not clearly show what eats what.   Its usual to add arrows to show food moving through the food chain.   The arrow   means   'is eaten by'.

This is one way of drawing a food chain, but it isn't an easy way!   When biologists want to draw a food chain, they normally just write the name of each living thing involved instead of drawing a picture.   This makes it much simpler.  

For example, a biologist would record the food chain above as:

This food chain tells the reader that grass is eaten by a pig and a pig is eaten by a tiger.

Try the examples below.

A food chain should begin with a producer. Here is another example for you.

In the Exercise, there are five, nearly complete food chains.   Each food chain has one living thing missing.   Think about the environment that each feeding relationship is from and fill in the name of a living thing that would fit in. Go to the Exercise.
