1. Types of Ecosystems

2. Review Abiotic + Biotic = Ecosystem Producers = plants (make their own food) Consumers = organisms that eat producers Decomposers = Organisms that break down all other organisms Herbivore = plant eaters Carnivores = meat eaters Omnivores = eat meat and plants

3. Types Tundra Coniferous Forest (Taiga) Temperate Forest Tropical Rain Forest Grasslands Deserts Wetlands Aquatic

4. Tundra *North America, Europe and Siberia *Long, cold winters (ground is frozen) *Short growing season- 60 days *Lichens, mosses, grasses, reindeer, musk oxen, caribou wolves, lemmings, snowy owls etc. **Alaska & high mountain elevations in the West

5. Taiga Stunted trees (evergreen forest) North America, Europe and Asia Cold winters (not as cold as the tundra) 120 growing days Pines, firs, spruce, willows, birches, moose, wolves, bears deer, elk, rodents etc. **NE US, and Alaska

6. Temperate Forest Summers are hot and humid, winters are cold 75-150cm of rainfall each year Oaks, maple, hickory, beech, chestnut, ferns, mosses, wolves, gray foxes, bobcat, deer, raccoons etc. Eastern North America and Europe **Central and Midwestern states

7. Tropical Rainforest 200-400cm of rainfall each year 25degrees Celsius year round North America, South America, Asia Flying squirrels, ants, termites, bees, monkeys, vines **Hawaiian Islands

8. Grasslands/Prairies Asia, North America, South America and Africa 25-75 cm of rainfall a year Grasses, wildflowers, coyotes, badgers, rattlesnakes, lions, various birds, zebras, giraffes etc. **Midwestern and Western States

9. Deserts Less than 25cm of rainfall a year North America (Mexico to Washington), Africa, South America, Asia and Australia Very hot during the day, extremely cold at night Cacti, yucca, mesquite, sagebrush, lizards, snakes, spiders, insects, etc. **SW US

10. Wetlands Located near water sources All over the world Frogs, newts, squirrels, chipmunks, deer, grasses, cattails, ducks etc.

11. Aquatic Temperatures are typically constant through out the year All water environment 75% of the world is an aquatic biome Fish, birds, whales, sharks, dolphins, cattails, algae, kelp, coral etc. Fresh water or marine (salt water)
