TCSS Biology Unit 5 – Ecology Information Milestones Domain/Weight: Ecology 25% Georgia Performance Standards: SB4. Students will assess the dependence of all organisms on one another and the flow of energy and matter within their ecosystems. A. Investigate the relationships among organisms, populations, communities, ecosystems, and biomes. B. Explain the flow of matter and energy through ecosystems by arranging components of a food chain according to energy flow, comparing the quantity of energy in the steps of an energy pyramid, explaining the need for cycling of major nutrients (C, O, H, N, P). C. Relate environmental conditions to successional changes in ecosystems. D. Assess and explain human activities that influence and modify the environment such as global warming, population growth, pesticide use, and water and power consumption. E. Relate plant adaptations, including tropisms, to the ability to survive stressful environmental conditions. F. Relate animal adaptations, including behaviors, to the ability to survive stressful environmental conditions. Purpose/Goal(s): Students should be able to: Students will assess the dependence of all organisms on one another and the flow of energy and matter within their ecosystems. Students will investigate the interdependence of organisms within an ecosystem and the connections between ecosystems on Earth. Students will explain flow of matter and energy through ecosystems. Students will comprehend successional changes in an ecosystem after a disturbance. Students will analyze the effects humans have had on their environment and possible solutions to human-made environmental problems. Students will explain how animal and plant adaptations help species to survive in a changing environment.
