Detailed explanation-1: -Plants make their food from energy from the sun. Animals get their energy from the food they eat. Animals depend on other living things for food.
Detailed explanation-2: -It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
Detailed explanation-3: -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-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: -Energy from the Sun fuels life on Earth Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere.
