However, the term "biotic" could be used to describe the living organisms and their interactions with each other and their environment. Other possible synonyms could be "faunal" or "floral," which refer to the animal and plant life in a specific area. Another term could be "ecological," which describes the relationships between living organisms and their environment. These synonyms can help to describe the biological aspects of a specific location or ecosystem.
