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 convert sunlight into the energy stored in their food. Plants also provide food for others. The plant is then fed to the next part of the food chain. 3 Plants are eaten by animals.

Detailed explanation-3: -Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.
