• A biome is determined mainly by its climate-like temperature and rainfall.
• Each biome has a different climate, which, in turn, affects the soil.
• The earth’s land areas are divided into 6 major biomes.

2. CONIFEROUS FOREST2. CONIFEROUS FOREST
• Confers = cone-bearing trees (pines, fir)
• Cold climate
• Dense forests (tree tops block out a lot of sunlight)
• Grasses, small trees cannot grow – only some shrubs, ferns and mosses thrive.
• Animals such as squirrels, moose, birds, and insects live here.
