Here's why:
* Photosynthesis: Plants use sunlight, water, and carbon dioxide to produce glucose (a sugar) and oxygen.
* Consumers: Animals and other organisms that cannot produce their own food are called consumers. They obtain their energy and nutrients by consuming other organisms, like plants.
* Glucose as Food: Glucose is a simple sugar that provides energy to consumers. It is broken down through cellular respiration, releasing energy that fuels all life processes.
So, the glucose produced by plants during photosynthesis is the primary source of energy for consumers.
