Biomes - Biotic Factors

Biome Physiological Plant Adaptation Typical Plants Physiological and Behavioral Animal Adaptation Typical Animals
Tundra Prostrate, small with shallow roots Lichen, moss, sedges, willow Keeping warm - large mammals, burrowing, hibernation or migration Mosquitoes, lemmings, snowy owls, musk oxen, caribou, waterfowl (swan, geese, ducks)
Coniferous forest Needle-leaves. Low diversity - high population density, mycorrhizal associations important to release nutrients Pine, spruce, fir, aspen Keeping warm - large mammals or hibernation Elk, deer, wolves, lynx, hare, rodents (red-backed vole)
Deciduous forest Broad-leaved hardwood trees, understory shrubs Maple, beech, alder Large and small mammals, neotropical birds Elk, deer, raccoon, salamanders
Grassland and Savannas C4 plants, grasses grow from base of plant, fire adapted Grass, herbaceous perennials, bunch grasses Large herds of grazing animals, burrowing mammals Bison, antelope, prairie dog
Tropical rain forest Nutrients stored in biomass. Mycorrhizal release of nutrients. Fantastic diversity - low population density. Big trees, figs, orchids, epiphytes Canopy, understory, basement Termites, bats, primates, parrots
Desert CAM plants, succulents, deciduous leaves, small hairy or resinous leaves, widely scattered Cactus, paloverde trees, creosote bush. Metabolic water, nocturnal, diverse arthropod and reptile populations Kangaroo rats, reptiles, scorpions, ants
