1. Create a study guide based on the Key Concepts listed at the beginning of the chapter on page 6. For each point, create three or four subpoints that provide further information, relevant examples, or explanatory diagrams.

CHAPTER 1 Understanding Biodiversity
KEY CONCEPTS
After completing this chapter you will be able to:
- describe the nature of biological diversity and the biological species concept
- outline some of the primary human-caused threats to Earth's biodiversity
- explain the principles of taxonomy and phylogeny and the concepts of taxonomic rank
- describe and compare traditional and modern biological classification systems
- outline some of the key features used to classify all living organisms into six kingdoms
- construct and apply dichotomous keys for the purpose of identifying species
- use appropriate sampling methods to collect specimens from an ecosystem and classify them using scientific criteria
2. Return to the Starting Points questions at the beginning of the chapter on page 6. Answer these questions using what you have learned in this chapter. Compare your answers with those that you gave at the beginning of the chapter. How has your understanding changed? What new knowledge and skills do you have?
STARTING POINTS
Answer the following questions using your current knowledge. You will have a chance to revisit these questions later, applying concepts and skills from the chapter.
1. How many different kinds of living things do you think there are on Earth? How might this diversity be important or valuable?
2. How do you think organisms can be distinguished from one another?
3. What do you think are the benefits of naming and classifying (or grouping) living things? How might this be accomplished?
Grade 11 Biology can lead to a wide range of careers. Some require a college diploma or a Bachelor of Science (B.Sc.) degree. Others require specialized or post-graduate degrees. This graphic organizer shows a few pathways to careers mentioned in this chapter.
