生物体的新陈代谢是生命的基础。新陈代谢率(单位时间内产生的能量)的增长速度比生物体的质量慢。当这种现象被考虑到不同物种时,它被称为种间异速尺度,其原因尚不清楚。我们认为,种间异速结垢的原因是构成食物链的生物体固有的生理和适应机制的总效应。这些机制的运作被任何生物的一个主要目标--成功繁殖--联合在一起。每一个有机体和整个食物链的基本需要就是所有有机体调整其新陈代谢速率的共同标准。在这篇文章中,我们考虑单细胞生物,而第二篇论文更详细地研究了多细胞生物和整个概念。在这里,我们利用所提出的概念和实验验证的五种不同单细胞生物的生长模型,获得了生长结束时的异速指数为0.757,生长开始时的异速指数为0.853。这些结果符合实验观察,并证明了我们的理论,即食物链中成功繁殖的要求是形成种间异速尺度的一个重要因素。

英文摘要:
  Metabolism of living organisms is a foundation of life. The metabolic rate (energy production per unit time) increases slower than organisms' mass. When this phenomenon is considered across different species, it is called interspecific allometric scaling, whose causes are unknown. We argue that the cause of interspecific allometric scaling is the total effect of physiological and adaptation mechanisms inherent to organisms composing a food chain. Together, the workings of these mechanisms are united by a primary goal of any living creature - its successful reproduction. This primary necessity of each organism and of the entire food chain is that common denominator, to which all organisms adjust their metabolic rates. In this article, we consider unicellular organisms, while the second paper studies multicellular organisms and the entire concept in more detail. Here, using the proposed concepts and experimentally verified growth models of five different unicellular organisms, we obtain close to experimental findings values of allometric exponents of 0.757 for the end of growth and 0.853 for the beginning of growth. These results comply with experimental observations and prove our theory that the requirement of successful reproduction within the food chain is an important factor shaping interspecific allometric scaling.
