Interaksi Makhluk Hidup dengan Lingkungan (Part 3) Aliran Energi Dalam Ekosistem

The video discusses the importance of nutrients for all organisms on Earth, explaining how energy is derived from food. It introduces the concept of energy flow between organisms through the processes of eating and being eaten, highlighting three forms of energy flow: food chains, food webs, and food pyramids. The food chain is defined as a sequence of organisms where each is eaten by the next, starting with producers like plants that create their own food through photosynthesis. Consumers are categorized into primary, secondary, and tertiary based on their position in the food chain, with decomposers like bacteria and fungi breaking down dead organisms. An example of a food chain in a garden ecosystem is provided, illustrating the flow of energy from sunlight to various consumers and decomposers.
