1. Biomes of the World

2. Two major Types of Biomes 1. Terrestrial Biome – Those biomes found on land, mainly characterized by plant life. 2. Aquatic Biome – Those found in water, mainly characterized by physical features.

3. Biomes are characterized by 1. Climate 2. Vegetation 3. Animal Life

4. Major Land Biomes 1. Tropical Rain Forest – Found near the equator. Receives large amount of rain and is mainly dominated by very tall trees. 2. Deserts- Found between 15 0 and 30 0 north and south. Terrain is mainly rock, sand, and poor soil. Very little rainfall so plant life is very specialized.

5. Major Land Biomes 3. Temperate Deciduous Forest - Found up to about 60 0 north and south. Has cold winters, warm summers, and abundant rainfall. Dominant life form is the deciduous tree that must lose its leaves each winter.

6. Major Land Biomes 4. Grasslands – These biomes have the most fertile and deepest top soil. They are mainly used for agriculture. Called the bread baskets of the world.

7. Major Land Biomes 5. Chaparral - Temperate shrub land biome. Dominated by short shrubs, which are adapted to destruction by fire. A dry region that does not have much precipitation in the summer.

8. Major Land Biomes 6. Temperate Rain Forest – Found on the West coast of North America. High amounts of rain all year and has a temperate climate. Dominated by tall coniferous trees. These trees do not lose their needles.

9. Major Land Biomes 7. Taiga – This is a northern coniferous forest. Long cold winters, short growing season. Most precipitation falls as snow. Coniferous tree needles are designed to maximize water retention.

10. Major Land Biomes 8. Tundra – Found far north. This is a treeless biome. Most of the year it is dark and dry, for a few weeks in the summer they have 24 hours of sunlight.

11. Freshwater Biomes Consists of fresh water found in lakes rivers streams and bogs. They contain a very small portion of the earth’s water. Provide habitats for a variety of fish, insects, algae, and plants. Consists of fresh water found in lakes rivers streams and bogs. They contain a very small portion of the earth’s water.

12. Marine Biome There are 5 major types of Ocean Biomes: There are 5 major types of Ocean Biomes: 1. Coastal Waters 2. Near Shore Zones 3. Coral Reefs 4. Open Ocean 5. Vent Communities

13. Coastal Waters Shallow enough to allow sunlight to reach a variety of forms of algae. Shallow enough to allow sunlight to reach a variety of forms of algae. Animals must survive exposure to both air and water because of tides. Animals must survive exposure to both air and water because of tides. This is known as an inter-tidal zone This is known as an inter-tidal zone

14. Coastal Waters

15. Near Shore Zone Found out beyond coastal waters. Found out beyond coastal waters. It is more stable because it is not affected by the tides. It is more stable because it is not affected by the tides. Organisms are mainly aquatic Organisms are mainly aquatic Abundant quantities of kelp. Abundant quantities of kelp.

16. Near Shore Zone

17. Coral Reefs Found in warm water. Found in warm water. Reefs formed from the skeletons of various species of coral. Reefs formed from the skeletons of various species of coral. A very diverse variety of plants and animals. A very diverse variety of plants and animals.

18. Coral Reefs

19. Open Ocean Large quantities of different species of small microscopic organisms: phytoplankton, zooplankton. Large quantities of different species of small microscopic organisms: phytoplankton, zooplankton. Various species of fish and sea mammals rely on phytoplankton and zooplankton. Various species of fish and sea mammals rely on phytoplankton and zooplankton.

20. Open Ocean

21. Vent Communities Lie in the great of the ocean. Not much life here, but more than scientists once thought. Lie in the great of the ocean. Not much life here, but more than scientists once thought. Very cold temperatures and no sunlight. Very cold temperatures and no sunlight. Vents are openings in the earths crust that provide heat and nutrients for very specialized organisms.

22. Vent Communities

23. Requirements of a Biome 1. Nutrients 2. Energy – sun 3. Water 4. Temperature Range.
