7538836429TundraCold, treeless biome with low-growing vegetation. Soil is frozen. Permafrost is present. Annual Temperature is -6.7 degrees Celsius0
7538836430Boreal Forest (Taiga)Very cold climate, plant growth constrained by temperature, not precipitation. Soil is nutrient poor due to slow decomposition. Annual precipitation is 31.8 cm1
7538836431Temperate RainforestModerate temperatures, high precipitation. Is a coast biome. Nearly a 12 month growing season. Supports growth of very large trees.2
7538836432Tropical Seasonal ForestReceives over 100 meter of rain. Broad leaf deciduous trees. Warmer summer temperatures favor decomposition so soils generally contain more nutrients.3
7538836433Temperate ShrublandHot, dry summers and mild rainy winters. 12 month growing season, but plant growth is constrained by low precipitation in the summer and by relatively cold temperatures in winter. Plants of this biome are well adapted to both fire and drought.4
7538836434Temperate GrasslandAnnual Precipitation is 80 cm. Cold, harsh winters and hot, dry summers. Plant growth is constrained by both insufficient precipitation in summer and cold temperatures in winter.5
7538836435Tropical RainforestAverage annual temperatures exceed 20 degrees Celsius. Precipitation occurs frequently. Biome is warm and wet with little temperature variation. Have more biodiversity per hectare than any other terrestrial biome. Contains 2/3 of Earth's terrestrial species6
7538836436Tropical SavannasAnnual temperature of 28.6 degrees Celsius. Soils is fairly fertile and can be farmed due to high decomposition rates but low amounts of precipitation constrains plants from using the soil nutrients that are released.7
7538836437DesertHot temperatures and extremely dry conditions. Cacti and succulent plants are well adapted to this biome.8
7538836438Freshwater WetlandsSubmerged or saturated by water for at least part of each year. Shallow enough to support emergent vegetation. Includes swamps, marshes, and bogs.9
7538836439Swampswetlands that contain emergent trees10
7538836440Marsheswetlands that contain non woody vegetation, such as reeds and grasses.11
7538836442Salt marshesfound along the coast in temperate climates and contain non woody emergent vegetation.12
7538836443Mangrove Swamptropical and subtropical coasts that contain trees whose roots are submerged in water. Mangrove trees are salt tolerant and help protect coastline from erosion and storm damage.13
7538836444Coral Reefswarm, shallow waters beyond shoreline. Most diverse marine biome.14

Need Notes?

While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
