The diagram shows a number of food chains related to each other. This is called a food web. 

Use the food web to answer the following:   

a)
Name a producer in the food web. ____________________
 
b)
Which two animals in the food web are not eaten by other animals?
 
1.  ____________________  and  2.  ____________________
 
c)
Name a carnivore in the food web. ____________________
 
d)
In the space below draw a food chain that is part of this food web.
The food chain must contain small birds.
 
e)		  
What do the "arrows" mean in a food chain or food web?

These ARB tasks explore feeding relationships through food chains, food webs, the roles plants and animals have in them and the impacts of change in a natural environment.
Each task requires students to interpret the scientific convention of arrows in feeding relationships as representing the flow of energy transferred from one species to another.
