Introduction to Ecology - Biology (Senior Secondary)

Every living thing relies on its surroundings to survive. This course teaches the core rules of ecology. You will study the factors that control the distribution of organisms across different habitats. We cover symbiotic interactions, the flow of energy through ecosystems, and the cycling of nutrients in nature. Understanding these principles is necessary for solving real environmental problems. You can apply this knowledge directly to careers in agriculture, forestry, conservation, and public health. This foundation helps you tackle urgent issues like pollution, climate change, and the destruction of habitats. Farmers and environmental managers use the rules of nutrient cycling to improve crop yields and protect wildlife. You will learn to identify the physical and biological factors that determine the survival of organisms. You will classify different symbiotic relationships, including mutualism and parasitism. You will trace the transfer of energy through food chains and food webs. You will also map out major nutrient cycles, such as the carbon and nitrogen cycles, to see how matter moves through the environment. This course is strictly for senior secondary biology students preparing for final exams. It also benefits university students who need a review of basic ecological concepts. Anyone interested in environmental science or farming will find the lessons useful. The simple explanations make the science clear for anyone wanting to understand how the natural world works.
