Detailed explanation-1: -Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.

Detailed explanation-2: -Producers are organisms that can produce their own food. They usually include green plants. They trap the energy from the sun and use it to make food by the process of photosynthesis. All the other organisms depend on producers for food, since they are not capable of making food for themselves.
