The global distribution of ecosystems

The objectives for today's lesson were:

- to know that, on a world scale, climate is the main factor determining the nature and extent of natural vegetation cover.
- to understand the term ‘biome’.
- to learn the names of the world’s main biomes.
- to be able to describe the changes in vegetation cover from the equator to the polar regions.

This map shows the world's main biomes. Can you define the word 'biome'?
