NEET BIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -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-3: -The Sun in a food chain is the main source of energy. It is required in almost every food chain. Food chains include specific levels of organisms where energy can be transferred. Most food chains must begin with the Sun.

Detailed explanation-4: -All nutritional energy comes from the Sun: plants use chlorophyll to photosynthesize the Sun’s energy into plant energy, and then animals either feed on plants for that energy or they feed on the animals that have eaten that plant energy. The food chain begins with the Sun and then the energy flows to producers.

Detailed explanation-5: -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.
