Why this why now
This unit builds on pupils’ prior learning from Living organisms and their environments, where they explored how biotic and abiotic factors affect species survival. It deepens their understanding by examining the importance of maintaining biodiversity and the impact of human activities on ecosystems. As the final unit in the big question How do living things live together in their environments?, it reinforces the need for conservation and sustainable practices to preserve ecosystems and the complex relationships that support life.
Prior knowledge requirements
- Food chain diagrams show transfers of biomass.
- Food web diagrams represent several interconnected food chains within a community of organisms.
- Trophic levels are the stages in a food chain.
- Biomass is the amount of living or recently living matter.
- Biodiversity is a measure of the range of living organisms.
- It is important to preserve biodiversity to maintain a healthy environment.
- Pollinating insects are important in producing crops.
- The relationship between genes, chromosomes and DNA.
- The products of combustion.
- Which fuels are fossil fuels.

Maintaining biodiversity and human impacts
This unit explores trophic levels, biomass pyramids, and the efficiency of biomass transfers in ecosystems. It examines human impacts on biodiversity, factors affecting food security, and biotechnological solutions. Emphasis is on evaluating environmental changes and ethical considerations.
