Photosynthesis Concepts and Processes

The video explains how almost all life on Earth is powered by solar energy. Plants, algae, and some bacteria capture sunlight and convert it into chemical energy through photosynthesis. This process involves producing carbohydrates from water and carbon dioxide, releasing oxygen as a byproduct. Photosynthesis is essential for nourishing nearly all living organisms on the planet.
