  1. The World’s Biomes and Ecological Organization. Yea!

  2. Background… • Ecologyis the study of living things in their environment and how they affect each other.

  3. Background… • Ecological Organization • Living things can be studied at six different levels: • INDIVIDUAL: • An organism belonging to a particular species.

  4. Background… • Ecological Organization • POPULATION: • A group of organisms of the same species living together in a specific area. • The total count of individuals within a group.

  5. Background… • Ecological Organizations • COMMUNITY: • Made up of populations of different species living together in the same area. • These organisms usually interact and depend on each other.

  6. Background… • Ecological Organizations • ECOSYSTEM: • A system in which biotic (living) organisms interact with each other and their abiotic (nonliving) environment. • Abiotic environments include things such as sunlight, soil, moisture, temperature,and nutrients.

  7. Background… • Ecological Organization • BIOME: • More on this in a minute….

  8. Background… • Ecological Organization • BIOSPHERE: • The sum of Earth’s biomes. • The living part of the planet. • Extends from just above to just below Earth’s surface.

  9. Biomes • A group of ecosystems with similar climates and organisms. • Ecosystem - All the living and non-living things that interact in an area

  10. Biomes • Biomes are the regions of our planet which are best be defined by their climate, plant life and animal life.

  11. Biomes • What is the most important factor in forming or creating a biome? • C.D.

  12. Biomes • Climate! • Temperature and rainfall determine a biome. • Why? • C.D. • Level sticks

  13. Biomes • How many Biomes are there? • Scientists argue on the exact number, or different types of biomes in existence. • We are going to lump them into about 9.

  14. Biomes • Rain Forest Biomes • A forest that receives more than 2.5 meters (8 feet) of rain each year. • Tropical • Warm regions, close to the equator • Temperate • Land along the northwest coast of the US

  18. Temperate Rainforest Biomes

  19. Biomes • Desert • An area that receives less than 25cm of rain each year.

  22. Biomes • Grasslands • An area that receives between 25cm and 75cm of rain each year. • The main vegetation is grass or type of grass plants.

  24. Grassland Biome http://www.uwsp.edu/gEo/faculty/ritter/geog101/textbook/biogeography/biomes_grassland.html

  25. Biomes • Deciduous Forest • Has at least 50cm of rain each year. • Forests in which the trees lose their leaves each year. • Deciduous means "temporary" or "tending to fall off" (deriving from the Latin word decidere, to fall off).

  28. Biomes • Boreal Forest • Has at least 50cm of rain each year. • Forests contains Coniferous Trees • Seeds in cones and leaves shaped as needles • Winters are very cold.

  31. Biomes • Tundra • Extremely cold and very dry • Most soil exist as permafrost. • Frozen soil

  34. Biomes • Mountains and Ice • Mountains pass through several “biomes” as you travel from base to peak • Ice - well it’s Ice…’Nuff said. • Penguins and polar bears

  35. Biomes • Freshwater • Standing water • Ponds and lakes • Flowing water • Streams and Rivers

  36. Biomes • Marine • We have a whole presentation on that.
