XI. Structure and Function in Living Systems
A. Cells are the fundamental unit of life None None None
B. Living systems are organized by levels of complexity Producers, Consumers, Decomposers, Organisms and Migration (taxonomy) Organisms as examples Anatomy Screens (9 body systems)
C. Specialized structures perform specific functions at all levels of complexity None Animal Characteristics, Plant Characteristics Anatomy Screens (9 body systems), Dissection
XII. Reproduction and Heredity
A. Reproduction is essential for species’ survival Organisms and Migration (life cycle) Organisms (life cycle) Reproductive system
B. Characteristics of an organism result from inheritance and from interactions with the environment Organisms and Migration as examples Organisms as examples, New Species, Species Change None
C. Individual organisms with certain traits are more likely than others to survive and produce offspring Organisms and Migration as examples, Plant Adaptations, Animal Adaptations Organisms, New Species, Species Change, Plant and Animal Characteristics None
XIII. Regulation and Behavior
A. Living organisms strive to maintain a constant internal environment Animal Adaptations, Habitat, Organisms and Migration as examples Organisms as examples Hibernation, Feeding
B. Living organisms respond to external stimuli Animal Adaptations, Habitat, Organisms and Migration as examples Dependency Web Screens, Plant and Animal Characteristics, New Species, Species Change Behavior (Hibernation, Feeding, Mating, Vocalization, Jumping)
XIV. Populations and Ecosystems
A. Sunlight is the ultimate source of energy Food Chains, Web Energy, Photosynthesis Productivity None
B. Population growth and decline are dependent on various factors None Species Change, New Species None
C. In all environments, organisms with similar needs may compete with one another for resources including food, space, water, air, and shelter. Other relationships may be beneficial Food Chains, Food Web Game, Plant & Animal Adaptations, Habitat Dependency Types, Habitat, Food, Seed Dispersal, Pollination, Niches, Dependency Game, Ant Symbiosis None
D. Organisms within an ecosystem are dependent on one another and on nonliving components of the environment Food Chains, Producers, Consumers, Decomposers, Plant and Animal Adaptations, Habitat, Food Web Game Food, Habitat, Seed Dispersal, Pollination, Niches, Web Game, Ant Symbiosis None
XV. Diversity and Adaptations of Organisms
A. By classifying organisms, biologists consider details of internal and external structure Producers, Consumers, Decomposers, Organisms and Migration (taxonomy) Use Organisms as examples None
B. Organisms have a great variety of internal and external structures that enable them to survive Use Organisms and Migration as examples Use Organisms as examples Anatomy screens (9 body systems)
