Photosynthesis: The Process of Creating Energy in Plants and Algae

The video explains how organisms obtain energy, focusing on photosynthesis in plants and algae. Photosynthesis is an endothermic process where light energy converts carbon dioxide and water into glucose and oxygen. The video details the chemical equation and the role of chlorophyll in trapping light energy. It also highlights the importance of photosynthetic organisms in producing biomass, which serves as food for other organisms. The video concludes with a recap of the photosynthesis process and its significance.
