A look at a food chain on a farm that is based on a wheat crop. The wheat takes energy from the sun and turns it into lovely green growth. Eventually it comes to seed and provides the wheat we use to make bread and to feed animals. There are many animals and insects living in a crop such as wheat. The food chain begins with small insects such as aphids, which are eaten by bigger insects such as ladybirds. These are in turn eaten by small birds, which are themselves sometimes caught and eaten by the bigger birds of prey such as peregrine falcons, kestrels and buzzards.

This clip could be used as an introduction to learning about more complex food chains. Having watched the clips, pupils could be given the task of constructing a food chain including all of the living things featured. It could be used to introduce the terminology of producer and consumer, predator and prey. It could also be looked at when consolidating work about nutrition, habitats and the interdependence of living things.
