  1. Biomes Think back to ecosystems….

  2. Individual- 1 specific organism Population- all of 1 type of living organisms Community= Only the living factors Ecosystem= Living and non living factors Biome= Ocean Biosphere= Earth

  3. What are biomes? • Biomes are large regions of Earth. • Each biome has a certain kind of climate. Different communities of living things are found in different climates.

  4. Earth’s major biomes • Earth has six major biomes. • Write: • A biome is a large group of ecosystems that are similar is some ways. • The major difference is climate.

  5. World Biomes • Tundra • Taiga • Temperate Forest • Tropical Rain Forest • Grassland • Desert

  6. Think of some organisms that you might find in a desert….

  7. Deserts are the home to many living things. In fact, deserts are second only to tropical rainforests in the variety of plant and animal species that live there. • How do you think plants grow in a place that is very, very dry?  • Many of the fascinating features of desert plants are adaptations -- traits that help the plant survive in its harsh environment. Desert plants have two main adaptations:  • Ability to collect and store water    • Desert plants often look different than plants in any other biome.

  8. Think of some organisms that you might find in a grassland biome…

  9. Grassland biomes are covered with grasses, have very few trees, and have long periods with no rain. • Two examples are prairies and savannas.

  10. Think of some organisms that you might find in a forest biome…

  11. There are two types of forest biomes • Temperate forests- have four different seasons: summer, fall, winter, and spring. • It has animals such as deer, rabbit, skunks, squirrels, and bears. • Trees in these forests lose their leaves in the fall.

  12. Temperate forest food chain

  13. Rainforest biomes • Very rainy and hot. • Some get more than (240 in.) of rain each year! • This makes it summer all year. • There are also numerous types of insects. • Ecosystems can be as small as a puddle.

  14. Rainforest food pyramid

  15. Taiga • Taiga biomes have long, harsh winters and short, cool summers. • The taiga is dry. • Most of the precipitation is snow. • Most of the trees are pines, firs, and spruces.

  16. Gray Wolf

  17. Tundra • The tiaga’s climate is mild compared to the tundra. • The tundra is the Earth’s coldest biome. • The lower layers stay frozen all year long. • It has an average temperature of (-29 degrees F)

  18. Tundra food pyramid

  19. Inches of rain fall per year.

  20. Marine Biomes • Oceans cover 70 % of Earth. • In the oceans are marine biomes.

  21. Freshwater Ecosystems • Many bodies of water are made up of fresh water. • Streams, rivers, ponds, lakes, and wetlands are freshwater ecosystems.

  22. For Homework • Choice one of the biomes mentioned in this power point. • Come up with a few organisms living within the ecosystem (of your choice of biome) that would make a food chain. • Draw and color them. In one to two paragraphs tell how the following will affect the organisms within the ecosystem. • 1. A drought occurs • 2. Continuous rainfall
