Life in the Water *suitable for home teaching*

This Cape Farewell video clip shows that phytoplankton and zooplankton have a crucial place in the Arctic food chain which is highly sensitive to change. The Cape Farewell scientists need to study plankton to understand how they respond to global climate change.

Activity A - Food chains uses the Arctic food chains to show why a pyramid of biomass is more useful than a pyramid of numbers.

Activity B - Arctic food web develops ideas about food webs and encourages students to think about adaptations of species. The baleen whales (including the minke) are grazers: large, slow and filter lots of water. The killer whale is adapted to killing – it is fast and has sharp teeth.
