  1. Biomes

  2. Review Levels of Ecological Organization • Organisms make up a population. • Populations make up a Biological community. • Communities and the nonliving factors make up an ecosystem. • Ecosystems make up a biome. • Biomes make up the biosphere.

  3. Biome • A large group of ecosystems that share the same climate and have similar types of communities.

  4. Biomes Biomes are determined by: • climate 2) Plant species 3) Animal species

  5. CLIMATE • The average weather conditions including TEMPERATURE and PRECIPITATION. • What’s weather?? The condition of the atmosphere at a specific place and time.

  6. Quick How are Biomes determined? ? Climate Plant species Animal species

  7. There are Nine major biomes • Rain forest • Desert • Temperate Grassland • Tropical seasonal forest • Boreal Forest • Tundra • Temperate Forest • Temperate Woodland • Savanna These are the ones in the book So that’s what we're going with!

  9. RAIN FOREST • There are two types of rain forest. TROPICAL & TEMPERATE

  10. RAIN FOREST • A tropical rain forest’s climate does not vary much throughout the year. • It will have warm temperatures year round with lots of sunshine. • It also will have up to 400 cm. of rainfall in a year. • The world’s rain forest are located along the equator.

  11. RAIN FOREST • The largest variety of species is also found in the tropical rainforest. • The distinct layers of the rain forest provide for abundant plant life and habitats for many animals.

  12. RAIN FOREST • Temperate rain forest are similar to tropical in that they receive up to 300 cm. of rainfall a year. • However it is too far north to have the warm year round temperatures. • They are located on the Northwestern coast of the United States.

  13. Desert • This biome has extreme temperatures. Hot in the day and cool to cold at night. • It receives less than 25 cm. of rainfall in a year. And some years may receive none.

  14. Desert • There is little vegetation in the desert biome due to the high evaporation level. • The organisms that live in the desert are adapted to the lack of rain and extreme temperatures.

  15. Grasslands • Grasslands receive about 25 to 75 cm of rain each year. • Typically they are populated by grasses and other non-woody plants. • Prairies are located in the middle latitudes while savannas are located closer to the equator

  16. Grasslands • Grasslands are home to many of the largest animals on earth bison antelopes zebras rhinoceros giraffes kangaroos

  17. Deciduous Forest • The temperatures in a deciduous forest will vary throughout the year with warm summers and cold winters. • This biome will receive at least 50 cm of precipitation each year.

  18. Deciduous Forest • The trees in this forest are deciduous, that is they shed their leaves and grow new ones each year. • There are a number of animal species in this biome, however during the winter some birds will migrate and other animals will hibernate.

  19. Boreal Forest • Boreal forest are also referred to as the taiga biome. • It is characterized by a cold, harsh climate with low rate of precipitation. • The forests contain mostly coniferous trees.

  20. Boreal Forest • This biome span the northern part of North America, Europe, and Asia. • The Boreal forest is the largest biome on earth. • Its animal diversity is somewhat limited due to the harsh winters.

  21. Tundra • The tundra is extremely cold and dry. • It is the coldest biome with very little vegetation. Mostly mosses, grasses, and a few small shrubs. • There is very little precipitation.

  22. Tundra • Most of the soil in the tundra called permafrost, is frozen all year. • The animals in this area grow thick fur coats to survive the winters.

  23. Water Biomes • There are two water biomes. FRESHWATER & SALTWATER • These biomes are affected by temperature, sunlight, oxygen, and salt content.

  24. Freshwater biomes • Ponds and Lakes which are bodies of standing, or still freshwater. • Streams and Rivers which are bodies of more rapid moving freshwater. • Estuaries which is the shallow sunlit water where the river meets the salt water of the ocean.

  25. Salt water biomes • This biome is also referred to as a marine biome. • Marine biomes vary according to the amount of sunlight, degree of water temperature, and amount of water movement. • There is also a wide variation of animal life throughout the different levels.
