Detailed explanation-1: -The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.

Detailed explanation-2: -Producers are organisms that produce their own energy from sunlight. Producers turn sunlight, water, and carbon dioxide into food in the form of a sugar.

Detailed explanation-3: -The energy is stored in the chemical bonds of the molecules, which are used as fuel and building material by the plant. The energy stored in organic molecules can be passed to other organisms in the ecosystem when those organisms eat plants (or eat other organisms that have previously eaten plants).
