  1. Biomes

  2. Introduction • A group of land ecosystems with similar climates and organisms is called a biome. • It is mostly climate conditions in an area that determine its biome. • We are going to talk about 7 land biomes and 3 aquatic biomes.

  3. Climograph • graph • shows a biome’s monthly temperature and precipitation data in a single year

  4. Abiotic Factors Physical or NONLIVING component of an ecosystem Rocks, Sand, Cliffs Snow, Rain, Hail Wind Sun, Heat, Cold

  5. Biotic Factors • Living Parts of an ecosystem • Plants • Animals • Bacteria

  6. How Organisms Adapt • What is an adaptation? • How can temperature affect the characteristics of an organism? • How can precipitation affect the characteristics of an organism?

  7. Rain Forest Biomes • Known for their abundance of • Rain • Plant life • Animal life • The climate (warm with plenty of rain) provides a great environment for plants. • The more plants there are the more animals that can be supported.

  8. Temperate Rain Forest • Found along the northwestern coast of the United States and New Zealand. • Twilight was set in a Temperate Rain Forest. • Has more moderate temperatures that change throughout the year. • Between 200-350 cm of precipitation. • Further from the equator than tropical rain forests.

  9. Tropical Rain Forest • Typically found near the equator between the Tropic of Cancer and the Tropic of Capricorn • The temperature range is between 20 and 25 degrees Celsius. ( 68- 77 degrees Fahrenheit) • Receive an average of 200 - 1,000 cm of precipitation each year

  10. Tropical Rain Forest • The abundant plant life provides habitats for many species of animals. • Millions of species of animals live here • Insects are a major food source • Probably contain more species of plants and animals than all the other biomes combined.

  11. Tropical Rain Forest • The tall tress in a tropical rainforest form a leafy roof called the canopy. • Under the canopy is a second layer of shorter trees and vines that form an understory. • The forest floor is nearly dark so only a few plants live there.

  14. Desert • Typically found between 25o and 40o latitude • Deserts are characterized by very dry climates. • They have a wide yearly temperature range. From -4 – 38 degrees Celsius. (24-100 F) • Receive less than 25 cm of rain each year. • The amount of evaporation is greater than the amount of precipitation

  15. Desert • Organisms must adapt to the lack of rain and extreme temperatures. • Stem of the saguaro cactus stores water • Gila monsters can spend weeks at a time in their cool underground burrows • Many other animals are most active at night

  18. Grassland Grasslands also known as prairie, pampas, steppes, and veldt, are areas that receive more rain than the desert but not enough to support trees. • Found on the interiors of continents between 30 and 50 degrees north and south latitude • Average temperatures are between -20 and 30 degrees Celsius (-4 and 86 F) • Receive 50-90 cm of rain each year • They have very rich soil • Home to many of the largest animals on Earth.

  21. Savanna • Grasslands that are closer to the equator • Warm temperatures with wet and dry seasons • Temperatures range between -16 and 34 degrees Celsius (3-94 degrees F) • Average precipitation is between 50-130 cm • Since there is more precipitation some trees can be found here

  26. Temperate Deciduous Forest • Where We Live! • Named for Deciduous trees that are found there • Trees that shed their leaves and grow new ones each year • Located between 30 and 50 degrees N and S Lat • Temperatures range from -30 – 30 degrees Celsius (-22 – 86 degrees F) • Average precipitation is between 75-150 cm

  30. Boreal/Taiga or Coniferous Forest • Known for its Coniferous trees • Fir, Spruce, and Hemlock • Further north than Deciduous Biome • Between 50 and 60 degrees latitude • Very cold winters—average temp between -40 and 20 degrees Celsius (-40 and 68 F) • Average precipitation between 30-90 cm
