| Term | Definition |
| tundra | regions in the far north and sometimes some southern high altitudes |
| tundra | Short growing seasons with brief intense sunshine, long cold winters with little snow and fierce wind |
| tundra | Tree-less and barren. The ground is covered by permafrost, so only a few plants such as Dwarf perennial shrubs, sedges, grasses, mosses, and lichens can grow |
| tundra | animals with compact bodies and thick fur coats such as arctic foxes, snow-show hares, and ptarmigan. Animals hibernate |
| taiga | Located on a broad belt in the Northern Hemisphere. Usually on the southern edge of the tundra. In EUROPE, ASIA, and NORTH AMERICA |
| taiga | Short warm summers and long severe winters |
| taiga | Dense coniferous and deciduous trees dominate the are, preventing most of the undergrowth |
| taiga | Moose, deer, elk, beaver, grizzly, and cougars. |
| temperate deciduous forest | throughout mid latitude regions |
| temperate deciduous forest | four distinct seasons, long summer days, and a 6 month growing season. Precipitation is constant throughout the year |
| temperate deciduous forest | Many species of deciduous trees, moss and lichens get the little remaining light that comes through the canopy |
| temperate deciduous forest | squirrels, deer, birds, raccoon, deer mice, insects, foxes, skunks, and black bears |
| Tropical Rain Forest | low lands along the equator. Takes up less then 10% of the world |
| Tropical Rain Forest | Hot with heavy rainfall, shows little seasonal variation |
| Tropical Rain Forest | Dense canopy and understory, many different plants, and trees are dominant. Canopy has emergent layer, upper, and lower. Then the below the canopy is called the basement |
| Tropical Rain Forest | Contains primates, amphibians, reptiles, arboreal rain forest animals, and many birds. |
| Temperate Grassland | West of the North American deciduous forests |
| Temperate Grassland | Very little precipitation, low winter temperatures, and may be relatively high in elevations |
| Temperate Grassland | Grasses and shrubs, with very fertile soil |
| Temperate Grassland | mostly hoofed mammals like cattle and sheep |
| Desert | 15-30 Latitude North and South |
| Desert | Low annual rainfall, high daytime temperatures, and a high rate of evaporation |
| Desert | No trees, only small plants that absorb water by having large root systems |
| Desert | Many small seed eating animals that are nocturnal go into a state of estivation, which is similar to hibernation for animals in hot and dry weather |
| Temperate Rain Forest | Located in the pacific northwest of the US |
| Temperate Rain Forest | Seasonal; warmer than normal winters; cooler than normal summers; high levels of precipitation; Affected by presence of Pacific Ocean |
| Temperate Rain Forest | Old growth forests of conifers; Redwoods, pines, spruces, firs, etc.; Ferns and mosses are common on ground level |
| Temperate Rain Forest | elk and deer; Many types of forest birds; Insects; Rodents; Fewer arboreal vertebrates than the tropical rain forest |
| Tropical Deciduous Forest | India, Southeast Asia, and Australia |
| Tropical Deciduous Forest | Warm year-round with little seasonal variation; Wet and dry seasons but enough moisture to support trees |
| Tropical Deciduous Forest | Many tree species are thorny to prevent to prevent browsing; dense undergrowth; Jungle like |
| Tropical Deciduous Forest | large herbivores (various deer species); Tigers; reptiles common; many bid species |
| Chaparral | Located in Southern California; Mediterranean region; South Africa; Chile; Western Australia |
| Chaparral | Dry summers and wet winters; Warm with limited variation in temperature; Fires are a normal part of this biome |
| Chaparral | Small trees and shrubs with waxy leaves; Fire adapted; Thick underground stems |
| Chaparral | Reptiles and rodents common; Burrowing animals predominate |
