Biomes • What is the difference between a Biome and an Ecosystem? • Biosphere • Biome Ecosystems are • Ecosystem part of Biomes • Community • Population
Biomes • Ecosystems are grouped into a larger biome • Depends on the climate and the type of plants in that area • 2 types: Terrestrial Biomes (on land) Aquatic Biomes (in the water) The species that live In each biome are different, but may look and act similar to species in other biomes. Because of similar niches in each biome.
An ecosystem is all the living and nonliving factors that affect an organism. • A biome is a major region that is characterized by its climate,soil type(s), and the dominant plants, animals, and other organisms that live there. A biome is made up of many individual ecosystems.
Types of Biomes • Mountains • Tundra • Desert • Chaparral • Grasslands: Temperate Grassland, prairie, plains, savanna • Taiga/Coniferous Forest • Temperate Deciduous Forest • Tropical Rainforest • Polar ice

Climate • Weather conditions over a long period of time
Latitude and Altitude Affect the Climate • Gets colder the higher up you go (altitude) • Gets colder the farther north/south of the equator you go (latitude) • Most of food on Earth is grown between 30-60 degrees north and south of the equator • -- Do we live in this latitude??--
Climatograms • A climatogram is a graph that shows average monthly values for two factors: temperature and precipitation. • Temperature is expressed in degrees Celsius and is plotted as a smooth curve. • Precipitation values are given in centimeters and are plotted as a histogram.
Tundra • Arctic tundra can be found in Antarctica and the North Pole, North of the Arctic Circle. • Grass, lichen and herbs • Permafrost – layer of soil that is always frozen. • Very short warm season that is very wet • Many insects during warm season
Taiga • The word taiga means, "marshy pine forest" in Russian. • one of the most fragile biomes. • Spruce and Fir trees • Found in Northern Hemisphere. • Growing season very short • Nearly constant daylight in summer • Many lakes and swamps
Temperate Forest • climate and amount of sunlight can vary tremendously between each season. • four types: Deciduous forest, Evergreen forest, temperate rain forest, and mixed evergreen and deciduous forests. • Deciduous trees, lose their leaves in fall.
Grasslands • Grasslands are characterized by their tall, perennial grasses and lack of trees. • 2 Types :Tropical grasslands , between the Tropic of Cancer and the Tropic of Capricorn.hot year-round, very dry, season of heavy rain. Temperate grasslands; north of the Tropic of Cancer or south of the Tropic of Capricorn, cold winters and hot summers. • cover a quarter of the land on Earth.
Savanna • Found near equator between tropical rain forest and desert biomes • Grass, scattered trees, shrubs, many with thorns • Many grazing animals • Have a wet and dry season • Plants and animals most active during wet season.
Chaparral smallest biome. grows between forest and grassland, or between desert and grassland biomes. Many plants and trees have leathery leaves, gnarled bark, and intimidating thorns.Often called “scrub”
Desert • Deserts take up 8.6 million square miles on Earth.
Desert • Get less than 25 cm of rain each year • Has little or no vegetation • Driest places on earth • Often located on the dry side of mountain ranges
Rainforest over half of the world's plant and animal species live here. All fit into only seven percent of the world's land. Found in: Central Africa, Southeast Asia, Philippines, New Guinea, Central and South America.
Rainforest • Layers: • Top – Emergent layer – tallest trees above rest of forest • Next – canopy – top of normal trees • Lower canopy – epiphytes – plants that grow on tree trunks – not soil - because light is so far from ground. • Understory – lowest level, much darker
