The sun is probably the most important source of renewable energy available today. Traditionally, the sun has provided energy for practically all living creatures on earth, through the process of photosynthesis, in which plants absorb solar radiation and convert it into stored energy for growth and development.
You won't believe these 10 facts about people. Energy homeostasis describes the ability of all living things to sustain the stability of internal functions. Most living things require certain internal conditions to survive.
By definition, homeostasis is the tendency of a system to maintain internal stability. It is essential to life in higher animals. When the external temperature rises, the human body responds by forming perspiration to maintain core temperature of 98.6 F, at which the body functions best.
