Detailed explanation-1: -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-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. A small proportion of this chemical energy is transformed directly into heat when compounds are broken down during respiration in plants.

Detailed explanation-3: -The food chain begins with the sun: plants get their energy by photosynthesizing sunlight into energy, and then herbivores eat those plants to get their energy. Carnivores who then eat the herbivores are getting that sunlight passed along from sun to plant to herbivore to carnivore.

Detailed explanation-4: -All food chains begin with the sun because the sun provides the energy which primary producers use to create biomass. This energy is supplied in the form of light and the light is absorbed by primary producers and used to perform photosynthesis.

Detailed explanation-5: -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?
