biological
The Spanish term 'biológico' translates to 'biological' in English. It is primarily used within the realms of biology and science, where it is used to describe anything related to life or living organisms. For example, a biological process in humans could include digestion, respiration, or reproduction. This term can also be used in a broader context to refer to things that are natural or organic, in contrast to items that are synthetically produced.
