Food chains are short because a lot of energy are expended at the trophic levels. Also it's because as we consider the many losses of energy such as heat and undigestable parts such as cellulose, hooves, and antlers. There aren't many energy to keep and pass on to the next level. Therefore, food chains contain usually 3-5 levels.
