An introduction to ecosystems, Food chains and food webs

This resource relates to the AQA specification for GCSE (UK) exams from 2018 onwards. The resource teaches students to be able to describe what an ecosystem is. The lesson looks at how energy is transferred through food chains and how small changes to parts of a food web can result in significant changes to the ecosystem. A role play task is used to illustrate these systems and a key word check list provided to guide pupils. Two support videos are included, as well as a link to enable learners to produce their own food webs.
