Final answer:
A snowshoe hare urinating on another hare is exhibiting a form of territorial marking, a way of communicating through chemical substances found in the urine.
Step-by-step explanation:
Animals, such as snowshoe hares, deposit chemicals to communicate with others of their kind, primarily to establish territories or attract mates. The urine contains pheromones and other substances that convey information about the individual's identity, reproductive status, and territory. Urination, in this context, is not just a waste-elimination process but a complex form of chemical communication used widely among animals, including domestic pets like dogs and cats.
