What term describes an organism that makes its own organic nutrients through photosynthesis?

• A. Producer
• B. Consumer
• C. Decomposer
• D. Hormone

Answer: (A)

An organism that makes its own organic nutrients through photosynthesis is a producer. Producers are autotrophs, meaning they can create energy-rich organic molecules from inorganic sources. In photosynthesis, they use light energy to convert carbon dioxide and water into glucose and other nutrients, releasing oxygen in the process. This ability places them at the base of the food chain, providing energy and organic matter for all other organisms in an ecosystem.

The other terms describe different roles: consumers rely on other organisms for their nutrients, decomposers break down waste and dead matter, and hormones are signaling molecules, not organisms.
