Which of these is a function of life?

Reproduction is a fundamental function of life because it enables organisms to produce offspring, ensuring the continuation of their species. It is one of the key characteristics that distinguish living organisms from inanimate objects. Through reproduction, genetic material is passed from one generation to the next, allowing for variation and evolution over time. This biological process can occur in various forms, such as sexual or asexual reproduction, depending on the species.

In contrast, competition, dominance, and isolation, while they may occur among living organisms, do not directly define life processes. Competition refers to the struggle between organisms for resources, dominance describes a hierarchical relationship between individuals, and isolation can refer to a lack of interaction among populations. These concepts can impact the survival and distribution of species but are not inherent functions of life itself. Thus, reproduction stands out as a core necessity for the survival and propagation of life.
