Detailed explanation-1: -Producers rely directly on solar energy. They absorb sunlight and convert it into nutrients through a process called photosynthesis. Producers, also called autotrophs, include plants, algae, bacteria, and fungi. Autotrophs are the foundation of the food web.

Detailed explanation-2: -Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Detailed explanation-3: -Producers: Producers are organisms that get their energy directly from the Sun. Their cells are able to turn sunlight into food through a process called photosynthesis. In photosynthesis, producers combine carbon dioxide, water, and sunlight to produce oxygen and sugar (their food).

Detailed explanation-4: -The sun is not a producer in the food chain. Nor is it a consumer nor a decomposer. All food chains though do begin with the sun.
