Detailed explanation-1: -Sunlight provides energy to plants for preparing food, and this energy is then passed on to the next trophic levels through a food chain.

Detailed explanation-2: -All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.

Detailed explanation-3: -The sun is the source of energy in the food chain. Solar energy is used by producers or plants to synthesize their own food through photosynthesis. The plants are then consumed by organisms of the higher trophic level leading to the transmission of energy. Was this answer helpful?

Detailed explanation-4: -The Sun’s energy is needed for plants to make food through a process called photosynthesis. In photosynthesis, green plants capture the Sun’s energy. They use it to make sugars from water and carbon dioxide. Plants are considered a producer in the food chain.

Detailed explanation-5: -The chemical energy of food is the main source of energy required by all living organisms. This energy is transmitted to different trophic levels along the food chain.
