Worksheet: Ecosystems
Summary of task
Students had completed a unit on ecosystems, including conducting field work in their local heathland and completing a case study on the Biosphere 2 experiment. They had investigated how matter and energy move through an ecosystem, and the different ways this can be represented.
This task was a revision exercise undertaken at the end of the unit. Students worked individually, with no access to resources, other than the Wetland Food Web diagram. They were given 40 minutes to complete the task. A recommended word count was given for the first question as a guide to the level of depth required by students in their answers.
