Green plants are the first living organism in a food chain. Where do plants get the energy that they pass along to the primary consumers in their food chains?

Green plants obtain energy primarily through the process of photosynthesis, where they convert sunlight into chemical energy. Using chlorophyll, they capture light energy and transform carbon dioxide and water into glucose and oxygen. This stored energy in the form of glucose is then passed along to primary consumers, such as herbivores, when they consume the plants. Thus, plants serve as the foundational energy source in food chains.
