Understanding small-scale ecosystems

Geography

Changes in small-scale ecosystems

The distribution and characteristics of global biomes

The factors affecting biome distribution

Using GIS to visualise the distribution and characteristics of global biomes

This unit teaches pupils about ecosystems and biomes at different scales. Pupils learn about the factors influencing biome distribution and the physical systems and processes regulating them. Pupils will also learn about the impact of population growth and resource extraction on biomes.
