Explanation:
Producers are unique set of organisms that begins a food chain or web. They are not dependent on any other organism for energy source (autotrophs). This is because of their ability to capture light energy from sunlight and use it to power the process of making their own food called PHOTOSYNTHESIS.
Photosynthesis is a unique feature of all autotrophic organisms like plants, planktons etc. It involves the use of an inorganic source (CO2) to synthesize organic food in the presence of sunlight. Plants and other producers obtain energy directly from the sun, hence, they are called PRODUCERS because they start a food chain in an ecosystem. Other organisms called CONSUMERS rely on them for energy.
