This occurs in very different ways in different kinds of living things. Nutrition2. Every organism needs nutrition for gaining energy. For example, use the key to answer the question. Viruses are considered non-living because they only exhibit characteristics of living organisms when they are occupying a host organism. Viral Structure Viruses lack the structure of living cells. In fact, there are seven characteristics that we can use to define 'life.' Complex organisms like mammals, birds, reptiles, etc., have a well-developed respiratory system and perform cellular respiration to produce energy. Evolution is so central to life that it is considered the core theme of biology.
