5. 1 Use a simple classification key to identify an unknown organism.

5. 2 Analyze structural, behavioral, and physiological adaptations to predict which populations are likely to survive in a particular environment. Adaptation = A characteristic that helps an organism survive and reproduce in its environment.

5. 3 Analyze data on levels of variation within a population to make predictions about survival under particular environmental conditions. Variation = refers to differences among organisms

5. 4 Identify several reasons for the importance of maintaining the earth’s Biodiversity = “bio” means life Important reasons for biodiversity. and “diverse” means different • Area has many different species, it is very diverse and healthy. • Area has few species = unhealthy environment. • When earth’s biodiversity decreases, it is harder for those species left to survive maintaining Earth’s biodiversity: 1. All organisms depend on all others for survival 2. We may be losing medicines 3. Better health for all organisms 4. We eat better 5. Future can also benefit from diversity

5. 5 Compare fossils found in sedimentary rock to determine their relative age. Relative Age of Fossils: 1. Fossils in same area or 2. Deeper the fossil/rock type of rock are same the older the fossil/rock age. Example 1: Example 2:
