REVIEW

  1. How many biomes can you name?
  2. What are the main contributing factors that divide these ecosystems into biomes?
  3. Which of these biomes has the highest productivity?
  4. Which has the highest and lowest soil nutrient content?
  5. Which are most useful to humans for agriculture?

There are other ways of representing the different biomes in the world besides showing it on a map as shown above.
Below are some examples where it took into account different factors to explain how the biomes are formed.

  • Can you draw up another representation of your understanding of biomes after looking at all these examples?
  • What other factors determine the distribution of these biomes besides those shown above?
  • What is the "value" of each biome? Are they all the same?
