The 10<span>% </span>Rule<span> means that when </span>energy<span> is passed in an ecosystem from one trophic level to the next, only ten percent of the </span>energy<span> will be passed on. An </span>energy pyramid<span> shows the feeding levels of organisms in an ecosystem and gives a visual representation of </span>energy loss<span> at each level.</span>
In order to identify the most recent common ancestor of an animal, the physical and genetic makeup of the organisms must be compared. The two organisms must have striking similarities in order to be considered as closely related.
Despite the difference in their size, the domestic ferret has a great resemblance with the features of an Eastern European polecat. In addition, they have the ability to cross-breed with polecats. Therefore, the most recent ancestor of the ferret is the Eastern European polecat.
