| Has warm temperatures that do not vary much throughout the year; very wet and humid; greater variety of species than any other biome | rainforest |
| Tallest layer of the rain forest that receives the most sunlight | emergent layer |
| Layer below the emergent layer and forms a leafy roof | canopy |
| Layer below the canopy containing shorter trees and vines | understory |
| Receives between 25 and 75 centimeters of rain each year; populated by grasses and many large herbivores; South Dakota is considered this biome (includes prairies) | grassland |
| Similar to grassland, but more rain and some small trees and shrubs; giraffes typically found here | savanna |
| Tree that shed their leaves and grow new ones each year | deciduous tree |
| Trees that produce seeds in cones and have leaves shaped like needles | coniferous tree |
| Has warm, rainy summers; very cold winters with heavy snow; trees produce cones with seeds that are eaten by many animals | boreal forest/taiga |
| Has extremely cold winters, warmer summers; windy; very dry; no trees, only low-growing plants; permafrost | tundra |
| Frozen soil | permafrost |
| Has warm summers, cold winters; receives at least 50 cm of precipitation per year; trees shed their leaves and grow new ones each year | deciduous forest |
