生物的能源无不是直接或间接地来源于太阳的辐射能。绿色植物吸收太阳能,同时利用光合作用过程中二氧化碳、水和无机物质生成化学能,成为含有能量的各种有机物质,而后在生态系统中为动物和其它异养生物所消耗,变成热散发出去。太阳能是一切生物能的源泉,其强度在大气层上限一带为1.9卡/厘米~2·分,称之为太阳系数。到达地 The energy of the living creature is not directly or indirectly from the sun’s radiation. Green plants absorb solar energy and use chemical energy from carbon dioxide, water and inorganic substances during photosynthesis to become energy-rich organic substances that are then consumed by ecosystems for animals and other heterotrophic organisms and become heat-emitting . Solar energy is the source of all bioenergy, its intensity in the upper limit of the atmosphere is 1.9 cal / cm ~ 2 points, called the solar coefficient. Destination
