Course Curriculum
| Energy Flow – Explains the transfer of energy within an ecosystem. Energy flows from producers (plants) to primary consumers (herbivores), and then to secondary consumers (carnivores). This topic explores the intricate pathways and principles governing energy transfer and its significance in ecosystem dynamics. |
| Food Chains and Food Webs – Analyze the relationships, energy transfer, and pyramid structures in food chains and webs. Explore examples of these structures in different ecosystems. |
| Carbon Cycle – Describes the movement of carbon through various reservoirs in the environment. This topic elucidates the processes of carbon absorption by plants through photosynthesis, its transfer to animals through consumption, and subsequent release back into the atmosphere through respiration and decomposition. Understanding the carbon cycle is essential in comprehending the global carbon balance and its implications for climate change. |
| Effects of Man on the Ecosystem – Examines the impacts of human activities on ecosystems. This topic investigates the detrimental effects of deforestation, including habitat loss and disruption of food chains. It also explores the consequences of pollution, such as industrial waste harming water bodies and endangering aquatic life. Conservation efforts are highlighted as vital measures to mitigate human-induced ecological damage and preserve the delicate balance of ecosystems. |
