Biomes

Bubble Map Complete the bubble map on the biomes Include Climate Temperature Rainfall Location One Fact

Background Biome: A large geographical area of distinctive plant and animal groups, which are adapted to that particular environment Biomes are largely determined by… Climate Rainfall Temperature Geography Landforms Altitude

Biomes of the world There are 3 broad biome classifications of the world, which can each be further subdivided: Marine biomes Freshwater biomes Land biomes Taiga Rainforest Tundra Desert Temperate Grasslands Savannah

How are Biomes Named? According to their plant life Plant life determine which organisms live there

Organisms in Biomes Plants & animals have adapted to specific environments Threatened by human activities

Biomes and Soil Deciduous Forest- good soil, lush plant life Deciduous = trees that drop their leaves Grasslands-good soil, lush plant life Desert-sandy soil, NOT much plant life Taiga-good soil, lush plant life (conifer trees) Tundra- permafrost of soil

Water Ecosystems Either Freshwater or Marine Freshwater = no salt Marine = salt water

Freshwater Ecosystems Includes lakes, ponds, rivers, streams and wetlands Distinguished by: Depth of the water How fast the water moves Availability of mineral nutrients, sunlight, and oxygen

Marine Ecosystem Identified by the presence of salt water Includes estuaries, coral reefs, oceans and ice caps

Tropical Rainforest Typically found near the equator Receives more than 200 cm of rain annually Temperatures typically fall between 20oC and 25oC for the entire year As many as 50% of all the world’s animal species may be found here

Tropical Savanna Grasslands with a few scattered trees Experience a wet and dry season Hot temperatures Annual rainfall is between 50 and 127 cm More species of grazing mammals than any other biome

Desert Typically found between 25o and 40o latitude Receives less than 25 cm of rain each year Temperatures typically range between 20oC and 25oC but some extreme deserts can reach temperatures higher than 38oC and lower than –15oC

Chaparral Found between 32o and 40o latitude on the west coast of continents Receives between 35 and 70 cm of rain, usually in the winter Extremely resistant to drought and weather events

Grassland Because of the dry climate, trees are found only near water sources such as streams Usually receives between 50 and 90 cm of rainfall each year Summer temperatures can reach up to 38oC, and winter temperatures can fall to –40oC

Temperate Deciduous Forest Moderate climate Most trees will lose their leaves in the winter Temperatures range between –30oC and 30oC Averages from 75 to 150 cm of precipitation Well developed understory

Temperate Boreal Forest Also known as Taiga Typically found between 45o and 60o North latitude Cold climate with summer rains Very few reptiles Limited understory Snow is primary form of precipitation (40 – 100 cm annually)

Tundra Means treeless or marshy plain Characterized by permafrost – permanently frozen soil starting as high as a few centimeters below the surface – which severely limits plant growth Winter temperatures average –34oC while summer temperatures usually average below 10oC Low precipitation (15–25 cm per year) but ground is usually wet because of low evaporation

Koppen classification The modified Koppen classification uses six letters to divide the world into six major climate regions, based on average annual precipitation, average monthly precipitation, and average monthly temperature. . .

A for Tropical Humid B for Dry C for Mild Mid-Latitude D for Severe Mid-Latitude E for Polar H for Highland (this classification was added after Köppen created his system)

Koppen Classification Each category is further divided into sub-categories based on temperature and precipitation. For instance, the U.S. states located along the Gulf of Mexico are designated as "Cfa." The "C" represents the "mild mid-latitude" category, the second letter "f" stands for the German word feucht or "moist," and the third letter "a" indicates that the average temperature of the warmest month is above 72°F (22°C). Thus, "Cfa" gives us a good indication of the climate of this region, a mild mid-latitude climate with no dry season and a hot summer.

North Carolina North Carolina is in the temperate deciduous biome 4 seasons every year Relatively large amounts of rain Animals and plants with special adaptations for changing seasons
