HTTP:: Blood Cell Size Influenced by Metabolism
--------
It is widely known among experts that smaller animals have a higher metabolic rate, which means that they essentially have to consume more food in order to be able to function. A famous example in this sense is the hummingbird, which has to consume several times its own weight in pollen each day in order to be able to move its wings so incredibly fast. According to a new scientific study, it would appear that, when supporting metabolism, the size of the blood cells truly matters. In fact, it plays a crucial role, LiveScience reports. When taking body size into account, smaller animals metabolize their nutrients faster than larger sized ones. It would appear that this simple fact is a determining factor in a very wide number of traits in the world as we know it, such as the life spans of individual species, or the dynamics of an entire ecosystem, including all its species. These concepts belong to the metabolic theory of ecology. While this is largely accepted among natura!
lists and biologists, the reasons why this scaling occurs have been a subject of heated debates for many years. According to one side of the argument, the scaling occurs because of the size and geometry of the supply networks, including the circulatory system. The scientists arguing for this viewpoint believe that there are only certain amo...
