1. Energy Flow in Ecosystems What Happened Here? While you were hiking, some hungry animals turned your campsite upside down.

2. Energy Flow in Ecosystems What Happened Here? Can you determine the order in which the organisms visited the campsite?

3. Food Web A food web consists of many interconnected food chains. Energy Flow in Ecosystems

4. Energy Pyramids What percent is lost from each level? What percent passes on to the next level? Energy Flow in Ecosystems

5. Water Cycle What are the three processes of the water cycle? Cycles of Matter

6. Carbon and Oxygen Cycles Producers, consumers, and decomposers all play a role in recycling carbon and oxygen.

7. Cycles of Matter Nitrogen Cycle In the nitrogen cycle, free nitrogen from the air is fixed into compounds. Consumers can then use these nitrogen compounds to carry out their life processes.

8. Cycles of Matter How does this picture show the water cycle, oxygen cycle, nitrogen cycle, and food chain?

9. Desert Organisms must be adapted to little or no rain and to extreme temperatures to be able to live in the desert. Biomes

10. How would you fill in the Venn Diagram with what you know about temperate and tropical rain forests? Biomes

11. Rain-Forest Biomes Rain forests are forests in which large amounts of rain fall year-round. Very little sunlight reaches the ground.

12. Tropical Rain Forests What are the four distinct layers of the tropical rain forest? Biomes

13. Grassland Biomes On the world map, identify the continents which the Rhea, Cassowary, and Ostrich inhabit. Biomes

14. Deciduous Forest Biomes Most of the trees in a deciduous forest have leaves that change color and drop to the forest floor each autumn. Biomes

15. Boreal Forest Biomes Tree species in the boreal forest are well adapted to the cold climate. Because the water is frozen for much of the year, coniferous trees have thick, waxy needles to prevent water loss.

16. Tundra Biomes Although the ground is frozen for most of the year, mosses, grasses, and dwarf willow trees grow here. Biomes

17. Mountains Mountains are not part of any major biome. Biomes

18. Biome Climates An ecologist collected climate data from two locations. The graph shows the monthly average temperatures in the two locations. The total yearly precipitation in Location A is 250 centimeters. In Location B, the total yearly precipitation is 14 centimeters. Biomes
