Study Notes
Biomes
-
Desert
- Temperatures vary greatly depending on location, from hot days to cool nights
- Rainfall - less than 25 cm per year, and may be unevenly distributed
- Soil - shallow and often loose, typically sandy
- Some deserts have soil with large amounts of salts
- Flora
- Plants are adapted to conserve water, such as cacti, shrubs and succulents.
- These plants are commonly found in areas with some rainfall.
- Fauna
- Desert animals are also adapted to conserve water, such as desert rodents, jack rabbits, lizards, snakes, and insects.
- Many desert animals use underground burrows for shelter and protection from the sun.
-
Tundra
- Temperatures range from -34°C to 12°C
- Precipitation ranges from 15 to 25 cm per year
- Soil - Permafrost, or permanently frozen ground, is a key characteristic of tundra biomes.
- Flora
- Plants are adapted to short growing seasons and cold temperatures, such as mosses, lichens, grasses, and dwarf shrubs.
- Fauna
- Animals are adapted to cold temperatures and harsh conditions, such as caribou, reindeer, arctic foxes, polar bears, lemmings, and snowy owls.
-
Alpine Tundra
- This tundra is located at high altitudes, meaning it occurs on mountains
- Temperatures are cold, windy, and arid
- Soil is thin and nutrient-poor
- Flora
- Plants are adapted to harsh conditions, such as grasses, small-leafed shrubs, heaths, and mosses and dwarf trees
- Fauna
- Animals are adapted to harsh conditions, such as mountain goats, sheep, elk, grouselike birds, and insects.
-
Grassland
- Temperatures vary depending on location, but typically are hot in the summer and cold in the winter
- Precipitation ranges from 25 to 75 cm per year
- Soil
- Typically rich and fertile.
- Flora
- Grasses are the dominant plant type, along with wildflowers and herbs.
- Fauna
- Grassland animals are adapted to grazing, such as bison, antelope, zebra, and gazelle.
- Predators such as lions, wolves, and coyotes.
-
Tropical Grassland (Savanna)
- Temperatures are hot year-round.
- Rainfall is seasonal.
- Soil is porous, with a thin layer of humus.
- Flora
- Grasses are the dominant plant type, along with scattered trees such as acacia, baobab, and river bushwillow.
- Fauna
- Savanna animals are adapted to grazing, such as elephants, giraffes, zebras, and buffalo.
- Predators such as lions, cheetahs, and hyenas.
Key Concepts
- Anti-freezing Chemical: A chemical that prevents the freezing of a plant's cells in cold temperatures.
- Specialized Root System: Roots that are adapted to access water and nutrients in harsh conditions.
- Transpiration Limit: The rate at which a plant can lose water through its leaves.
- Growing Close to the Ground: A strategy that allows plants to avoid cold temperatures and wind.
- Migration: Seasonal movement of animals from one location to another.
- Hibernation: A state of inactivity that allows animals to conserve energy during cold temperatures.
- Hides: Places where animals can find shelter and protection from predators and harsh conditions.
