Which term describes an organism that produces its own food, usually via photosynthesis?

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

Answer: (B)

Producers are the organisms that make their own food, forming the base of the food web. They use light energy to convert inorganic materials into organic matter, a process most people know as photosynthesis. This stored energy then supports all other organisms that rely on eating producers or other consumers. Plants, algae, and many bacteria are classic examples.

Some producers use photosynthesis, capturing sunlight to build sugars. Others, such as certain bacteria in deep-sea environments, use chemosynthesis to create food from chemical reactions instead of light. This still counts as producing their own food, just via a different energy source.

The other options describe organisms that do not produce their own food: consumers obtain energy by eating other organisms; decomposers break down dead material to recycle nutrients; parasites live on or in a host and rely on the host for nutrients.
