Autotrophs and Heterotrophs自养生物与异养生物
Organisms are divided into autotrophs and heterotrophs according to their energy pathways. Autotrophs are those organisms that are able to make energy-containing organic molecules from inorganic raw material by using basic energy sources such as sunlight. Plants are the prime example of autotrophs, using photosynthesis. All other organisms must make use of food that comes from other organisms in the form of fats, carbohydrates and proteins. These organisms which feed on others are called heterotrophs. 根据能量获取途径,生物可分为自养生物和异养生物。自养生物是能利用基本能量源如阳光,将无机原料转化为含能量的有机物的生物。植物是自养生物的典型例子,通过光合作用实现这一过程。其他所有生物都必须通过摄取其他生物所提供的脂肪、碳水化合物和蛋白质来获取能量。这些以其他生物为食的生物被称为异养生物。
