Web, and light, produces 6 molecules of oxygen gas, returns 6 molecules of water back to the cell, and produces one molecule of a simple sugar like glucose or fructose. Two reactions make up photosynthesis: the Light Reaction (abbreviated LR) and the Light Independent Reaction (abbreviated LIR). WebThe physiological response helps the organism maintain a constant internal environment (homeostasis), while a behavioral response allows it to avoid the environmental challenge—a fallback strategy if homeostasis cannot be maintained. The ways in which modern living organisms tolerate environmental conditions reflect the aquatic origins of life.

WebThe amount of light that can penetrate the surface is limited by a number of factors. For example, rays of light that approach at a low angle (at sunrise and sunset) are immediately reflected off the surface. Particles of organic matter and sediments from land also affect how much light is absorbed. WebOrganisms that make their own food by using sunlight or chemical energy to convert simple inorganic molecules into complex, energy-rich organic molecules like glucose are called producers or autotrophs. And here’s another quick Greek lesson: “auto” means “self” and “troph” still means “food.”
