What is a food chain? - Worksheet

A food chain is a fundamental concept in understanding how ecosystems function, illustrating the flow of energy from one organism to another. Students are encouraged to watch educational videos from BBC Bitesize and Yahoo Video Search to gain insights into this topic. After viewing the resources, they are prompted to discuss with a partner the content of the videos and then articulate, in their own words, the definition of a food chain. A food chain describes the sequence of who eats whom in the natural world, creating a linear network of relationships between producers, such as plants, primary consumers, like herbivores, and secondary consumers, including carnivores and omnivores.

When it comes to habitat selection, animals are often influenced by the availability of food sources. The choices animals make regarding their habitats are closely linked to where they can find the nourishment they need to survive. The worksheet encourages students to explore why certain animals choose specific habitats and to identify the connections between different food sources and the animals that rely on them. This learning activity, provided by Focus Education (UK) Ltd, aims to deepen students' understanding of ecological relationships and the importance of each species within a food chain.
