  4. Types of ecosystems: • Desert • Tundra/Alpine Tundra • Grassland/Savanna • Everglades

  5. Characteristics of a Desert • Very little rainfall (less than 10 inches/yr) • Very hot and dry • Animal adapt to heat by being nocturnal, active at night and rest during the day.

  6. Tundra/Alpine Tundra • Very cold. • Home to many types of plants and animals that have adapted to extreme conditions. • Very few trees survive, but there are many shrubs, mosses, and lichens. • Much of the land has ground that is permafrost, permanently frozen.

  7. Characteristics of a Grassland • Grassland biomes are large, rolling terrains of grasses, flowers and herbs. • Grasslands are found on every continent except Antarctica.

  8. Characteristics of Everglades • Called a "river of grass" because of its water and the thick sawgrass that grows there. • Home to hundreds of different organisms. • Over 43 different types of mosquitoes. • Mangrove forests help rid water of excess salt.

  9. Vocabulary • Adaptation occurs when plants and animals change in order to survive. • One way animals can adapt to the changing environment is by hibernating. • Plants have thick leaves in the desert to retain water.
