📖 1. Food Webs and Energy Transfer

🔑 Key Concepts & Definitions

• Food chains and food webs: A food chain is a linear sequence showing who eats whom in an ecosystem, while a food web is a complex network of interconnected food chains, illustrating multiple feeding relationships (source content).
• Energy flow in ecosystems: The transfer of energy from producers to consumers through feeding relationships, with energy decreasing at each trophic level due to metabolic processes and heat loss (source content).
• Poison accumulation in higher trophic levels: The process where toxins or pollutants build up in organisms as they consume contaminated prey, often leading to higher concentrations in top predators (source content).
• Examples of food webs: Illustrations of real ecosystems, such as a pond or forest, showing multiple interconnected food chains and the flow of energy among various organisms (source content).
