EVERYDAY SCIENCE

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

Detailed explanation-2: -3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. 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.

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.

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 sun is not a producer in the food chain. Nor is it a consumer nor a decomposer. All food chains though do begin with the sun.
