What is a biome? Definition: the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment.
So what? What does this mean and why do we care about biomes?
Characteristics of Every Biome Breakdown: Major world community Certain climate- temperature and precipitation in an area or region Organisms have adapted to the climate Many ecosystems Have changed over the history of the Earth Every square inch of the planet is located in a biome
Marine Bodies of salt water Covers 70% of the Earth’s surface Oceans Estuaries- where the mouth of the river meets the sea tides Salt Marshes- low, flat, poorly drained ground that becomes flooded by oceans and/or seas Coral Reefs Coastal areas
Coniferous and Boreal Forest (Taiga) Northern part of North America and Eurasia Contains conifer- trees that have leaves shaped like needles instead of flat leaves. These trees do not lose their leaves in the fall and winter. ~40˚C to 20˚ 30-90 cm (12-33 inches) of rain a year Warm and rainy summers Cold cold winters! Temperatures can reach a low of 65° F BELOW zero! Brrrr….
Arctic Tundra North Pole, Arctic Circle, and Greenland Covered in snow for most of the year Permafrost- The layer of earth located below the tundra is frozen all year long Less than 10 inches of precipitation a year ~40˚C to 18˚ Strong winds!! Create “white outs”, which occurs when the winds blow snow so much that it is hard to see.
Tropical Rainforest ~20°C to 25˚ 200-1000 cm (100-400 inches) of rain a year Basically, a lot of heat and a lot of moisture! The seasons do not change and the rainforests have rarely changed over the history of the Earth
Temperate Grassland South America, South Africa, Eurasia, and mid-west United States ~20˚C to 30˚ 50-90 cm of rainfall a year Tall grasses but no trees There are a lot of fires in this biome!
