Question: 1 / 400

What is a Producer?

An organism that feeds on other organisms for energy

An organism that decomposes organic material

An organism that makes its own food

A Producer is an organism that is able to create its own food through a process called photosynthesis. This process involves using sunlight, water, and carbon dioxide to produce glucose, a form of sugar that serves as the main source of energy for the organism. Producers are crucial for maintaining the flow of energy within an ecosystem, as they provide food for other organisms. Options A and B are incorrect because they describe consumers and decomposers, respectively. Option D is incorrect because it refers to a species' role in an ecosystem, rather than the specific function of producers.
