The correct answer is **D) Yes, all of the food consumed by humans is plants or gets energy from plants, and plants produce their own food through photosynthesis.**

Explanation: Humans depend on photosynthesis because it is a fundamental process that allows plants to convert sunlight into energy, producing oxygen and organic compounds. These plants are at the base of the food chain, directly supplying energy to herbivores, which in turn can be consumed by carnivores and omnivores, including humans. Even when humans eat animals, those animals ultimately depend on plants for their energy, either directly or indirectly. Therefore, all human food is linked to photosynthesis, making it essential for human survival and energy.
