Midterm 1 Study Guide 1Midterm 1 Study Guide CreatedTags Lesson 2  Explain why studying ecology helps us answer basic science questions and applied questions about our world. Be able to identify different types of ecosystem services. Explain how ecology relates to evolution. Lesson 3 How does the tilt and shape of the Earth create both the seasons and atmospheric circulation patterns? How does energy move in an ecosystem? Lesson 4 Use global, seasonal, or diurnal patterns of COemissions to infer the relative magnitudes of gross primary production and respiration. Explain how net primary production, ecological efficiencies, and top predator energy requirements set limits on the number of trophic levels in an ecosystem. Given a Sankey diagram or biomass or energy pyramid, predict the ecosystem it most likely describes. Lesson 5  Why does nutrient cycling matter to ecologists? What are the components of the nitrogen cycle?Feb 10, 2021 1123 AMMidterm 1 Study Guide 2 What are the the different formsnitrogen you might find in an ecosystem and whatthe processes convert nitrogen from one form to another? Convey in words and in a diagram (like a compartment model)to account for all nitrogen inputs and outputs for an ecosystem. Predict changes in pools or fluxes within a nutrient cyclebased on provided information. Explain how the addition of nutrients to an ecosystem acts as a disturbance, and consider ways to prevent human-caused nutrient inputs Lesson 6  Practice using what you know about nutrient cycling and energy flow to answer problem Lesson 7  Describe the similarities and differences among C3, C4, and CAM photosynthesis 2. Understand the implications of photorespiration for a plant 3. Relate the characteristics of C3, C4, and CAM photosynthesis to the ecology of the plants that use them 4. Use graphs of photosynthetic rate as a function of light and CO2 concentration to distinguish among C3, C4 and CAM plants  Distinguish between environmental adaptation and acclimation by organisms. Identify optimal growth temperature from thermal performance curves. Design experiments to test for evidence of adaptation or acclimation. Interpret thermal performance curves for evidence of adaptation or acclimationLesson 8Midterm 1 Study Guide 3 Lesson 9  Definelife history Describe is the relationship between birth rate, death rate and population growth Using age distribution, toinfer whether a population’s size is increasing, decreasing or stable Use data about a cohort, to determine the survivorship curve for a population Give examples of howknowledge of survivorship be useful for conservation
