Unit B: Diversity of Living Things
Chapter 1: Classifying Life’s Diversity
-
Genetic diversity, species diversity, and ecosystems diversity play crucial roles in
maintaining healthy ecosystems.
Biologists use appearance, breeding patterns, evolutionary relationships, and
DNA evidence to classify the wide variety of species on Earth. All organisms are
members of one of three domains. (Bacteria, Archaea, and Eukarya)
Specific Expectations:
In the chapter you will learn how to …
B1.1: Analyze some of the risks and benefits of human intervention to the biodiversity of
aquatic and terrestrial ecosystems. (1.4)
B2.1: Use appropriate terminology related to biodiversity. (1.1, 1.4)
B2.4: Create and apply a dichotomous key to identify and classify organisms from each
of the kingdoms. (1.3)
B3.1: Explain the fundamental principles of taxonomy and phylogeny. (1.1, 1.2)
B3.2: Compare and contrast the structure and function of different types of prokaryotes,
eukaryotes, and viruses. (1.3)
B3.5: Explain why biodiversity is important to maintaining viable ecosystems. (1.4)
