Detailed explanation-1: -If photosynthesizers were removed, the flow of energy would be cut off, and the other organisms would run out of food. In this way, photosynthesizers lay the foundation for every light-receiving ecosystem.
Detailed explanation-2: -The heat also keeps plants and animals warm. Without light from the sun there would be no photosynthesis and plants wouldn’t have the energy they need to make food.
Detailed explanation-3: -Over the last 30 years, researchers have discovered deep-sea ecosystems that live independent from the sun’s energy. These communities survive by utilising chemical rather than solar energy.
Detailed explanation-4: -Chlorophyll, needed to keep green plants alive, is made only in light. Because green plants are the only living organisms capable of producing their own food, all other living organisms depend on them either directly or indirectly for survival.
Detailed explanation-5: -Light energy affects water temperature, biological processes (such as the relationship between predators and prey) and plant photosynthesis and growth. Under natural conditions light is controlled by topography, cloudiness, vegetation cover, and seasonal patterns, like less daylight in the winter.
