Which of the following describes a primary producer?

A primary producer is an organism, typically a plant or similar autotrophic organism, that creates its own energy through photosynthesis. During this process, they convert sunlight, carbon dioxide, and water into glucose and oxygen, effectively capturing solar energy and turning it into chemical energy. This makes primary producers foundational to ecosystems, as they provide the energy necessary for other organisms within the food chain, such as herbivores and carnivores, to survive.

The other options describe different roles in the ecosystem: organisms that feed on other organisms are consumers, decomposers recycle nutrients back into the environment, and animals that feed on both plants and other animals serve as omnivores. However, it is the primary producer that uniquely performs the critical function of energy capture from the environment.
