Food chains show how food energy flows through an ecosystem. The arrows in a food chain show the direction of energy, for example:

| LEAF | GREENFLY | LADYBIRD | ROBIN | HAWK |
...shows that the energy produced by the leaves (using sunlight, water and air) is transferred to the consumers as they eat each other. The top predator is the hawk.
In the following questions, think about where organisms feed within the food chain and what would happen to the chain if they were taken out, say by disease.
