Pupils will learn about biomass transfer including calculating the efficiency of transfers between trophic levels. They will learn about human impacts on the environment, food security and biotechnology to help maintain biodiversity and achieve food security.

In the Climate change and greenhouse gases unit, pupils learnt about greenhouse gas emissions from transport and industry, and the use of renewable energy resources and changes to transport infrastructure that could reduce emissions.

In this unit pupils learn about the impact of agriculture and deforestation on biodiversity, and to more thoroughly consider the effects of climate change on biodiversity and food production.
