Photosynthesis and Cellular Respiration - Energy Cycle of Life

In this video, we explore two essential processes that keep plants, animals, and all life on Earth going—photosynthesis and cellular respiration. You’ll learn how plants make their own food using sunlight, carbon dioxide, and water, and how animals (including humans) use the food and oxygen from plants to create energy for their cells. Photosynthesis and cellular respiration form a perfect cycle that keeps the energy flowing through ecosystems. Watch to see how they’re connected and why they are vital for life as we know it! This video is perfect for middle school students and aligns with Next Generation Science Standards (NGSS) for Life Science. NGSS Standards Covered: MS-LS1-6: Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms. MS-LS1-7: Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism. MS-LS2-3: Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem. By the end of this video, students will have a solid understanding of how photosynthesis and cellular respiration work, their role in ecosystems, and how energy cycles through living organisms.
