4.4.2.5 Biodiversity is greater in ecosystems that provide a bigger range of different habitats which are home to larger populations of a variety of organisms. populations are in greater danger of dying out if an ecosystem is disrupted in some way. Ecosystems with high levels of biodiversity help to provide the resources needed to sustain life, including human life. Ecosystems with higher biodiversity offer economic benefits by sustaining the resources needed for agriculture, fishing and forestry. Define the term biodiversity. Explain how great biodiversity maintains food supplies and shelter for organisms, and maintains the physical environment. Describe examples of how a reduction in biodiversity can affect climate, food supplies for humans, useful chemical for the future etc. 1 Exhibition or video clips to show the variety of life, to include microorganisms and different plants and animals (links with 4.4.4.4, Identification and classification of living things) (see resources).

Teachit Science 4.4.2.6 Examples of human interactions with local ecosystems that can diminish or destroy biodiversity include: Explain what peat is and why it is important to preserve areas of peat. 1 Students research and discuss the concept of 'the tragedy of the commons' and how it applies to rainforests, the Arctic and the oceans.
