1. A biome is a group of ecosystems identified and named for a characteristic vegetation type.
  2. The predominant vegetation is strongly influenced by climatic conditions such as temperature and precipitation.
  3. A diagram of mean annual temperature versus mean annual precipitation can show how biomes and climates differ.
  4. There are not sharp boundaries between biomes - one biome gradually changes into another.


Use the diagram and the mean annual temperature and precipitation listed in the table to name the biome. Realize that there are not sharp boundaries between biomes and that one biome gradually changes into another as you change mean temperatures or precipitation.

More Directions:

Both plants and animals living in a biome adapt to the environment.

  1. Describe the climate conditions (hot, dry, cold in winter, etc) that might exist in each biome listed below.
  2. Describe the characteristics (not the names of plants and animals) that the plants and animals living there must have to survive.
