Ecology and Ecosystems Concepts

The video introduces the topic of ecology, emphasizing its significance in understanding the interactions between organisms and their environment. It outlines the learning objectives, including defining ecology, listing ecological interactions, and explaining energy flow. The lesson plan is detailed with a concept map, and the flow of energy is illustrated through a food chain example. Key ecological terms such as population, community, ecosystem, and biosphere are defined to provide a comprehensive understanding of the subject.
