The Cycle of Life: Matter and Energy in Ecosystems Review

The video tutorial explores the concepts of matter and energy in organisms and ecosystems. It explains how plants use photosynthesis to convert sunlight, water, and carbon dioxide into glucose and oxygen, making them producers. Consumers obtain energy by eating other organisms. The video also covers the digestion process and chemical respiration. It introduces ecosystems, food chains, and food webs, illustrating the flow of energy and matter. An interactive exercise encourages viewers to create a food web and identify producers and consumers in a chosen ecosystem.
