  • 1. Unit at a Glance Unit 1. Ecology [C6] Textbook Readings Chapters 50, 51, 52, 53, 54, 55 Essential Knowledge 2.A.1All living systems require constant input of free energy. 2.D.1 All biological systems from cells and organisms to populations, communities, and ecosystems are affected by complex biotic and abiotic interactions involving exchange of matter and free energy 2.D.2 Homeostatic mechanisms reflect both common ancestry and divergence due to adaptation in different environments. 2.D.3 Biological systems are affected by disruptions to their dynamic homeostasis. 2.E.3: Timing and coordination of behavior are regulated by various mechanisms and are important in natural selection. 3.E.1. Individuals can act on information and communicate it to others. 4.A.5: Communities are composed of populations of organisms that interact in complex ways. 4.A.6: Interactions among living systems and with their environment result in the movement of matter and energy. 4.B.3: Interactions between and within populations influence patterns of species distribution and abundance. 4.B.4: Distribution of local and global ecosystems changes over time. 4.C.4: The diversity of species within an ecosystem may influence the stability of the ecosystem. Laboratory Exercises AP® Biology Laboratory 11: Animal Behavior [C8] [C4] o Goal: To determine habitat preferences in the sow bug, to observe mating behavior in Drosophila (wet lab) AP® Biology Laboratory 12B & 12C: Aquatic Primary Productivity [C8] [C4] o Goal: To measure and analyze the primary productivity of natural waters, to understand the effect of light and nutrients on photosynthesis, to describe the relationship between dissolved oxygen and the processes of photosynthesis and respiration as they affect primary productivity in an ecosystem Equations and Formulas Rate and Growth o Rate o Population Growth o Exponential Growth o Logistic Growth o Primary Productivity Calculation Test Traditional test using a free response essay question and numerous multiple choice questions.
