CONCEPT MAPPING Use the following terms to create a concept map that shows how biomes can be classified based on climate: desert, savanna, tropical rain forest, temperate grassland, temperate deciduous forest, tundra, taiga, climate, arid, cold, temperate, tropical, hot, dry, trees, and grass.

Critical Thinking

Interpreting Graphics The rare species of squid in the photo below has several adaptations for living in very deep water. Explain some of the selective pressures that exist at great depths.

21. Analyzing Information Which biome occurs in all of the following locations: Spain, Australia, Canada, and the northeastern United States?

22. Evaluating Information Which soil is better suited for agricultural use: the soil of a tropical rain forest or the soil of a temperate deciduous forest? Explain your answer.

23. Inferring Relationships The organisms found near deep-sea volcanic vents do not use sunlight to get energy. What are possible energy sources for these organisms?

24. Predicting Results Would a herd of large herbivores be able to survive for many generations in a desert biome? Explain your answer.

25. Evaluating Viewpoints Imagine that a local government is debating whether a large freshwater wetland should be drained and filled in so that a new road can be built or whether the area should be turned into a wildlife refuge. Both of these options will have costs and benefits to the community. Draft some arguments that could be made for each side of the debate.
