Explanation:
The continual input of energy, mostly from sunlight, sustains the process of life. 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.
The circulatory system helps the excretory and digestive system do their jobs because the waste from the blood in the circulatory system is eliminated from the body through the excretory system, and the nutrients absorbed by the digestive system are transported through the blood.
