What does abiotically mean?
Abiotically is an adverb used to describe something occurring in relation to the nonliving components of an environment or without the involvement of living organisms. In ecology, abiotic factors include conditions such as temperature, light, water, soil composition, and wind. Saying that a process occurs abiotically emphasizes that its cause is physical, chemical, geological, or otherwise nonbiological rather than an activity produced by an organism. The word is especially useful in discussions of ecosystems, origins of life, geology, and planetary science, where distinguishing biological from nonbiological mechanisms is important. Its construction is transparent: it combines the adjective abiotic with the adverbial ending -ly. The related term biotic refers to living organisms or their interactions, so the contrast between abiotic and biotic helps organize much of ecological vocabulary.
adverbIn a way that relates to abiotic factors or processes, especially nonliving components of an environment or changes that do not depend on living organisms.
- In a manner relating to abiotic factors or processes; without biological or living-organism involvement.
"The minerals changed abiotically, without any contribution from living organisms."
"The rock surface was weathered abiotically by heat and wind rather than by organisms."
"These organisms survive by obtaining energy abiotically through mineral reactions rather than sunlight."
Abiotically is the adverb behind ecology’s basic split: the living world is biotic, while the nonliving world is abiotic.

Where does abiotically come from?
Abiotically was formed in English from the adjective abiotic and the adverbial suffix -ly. The underlying adjective comes from the prefix a-, meaning “without,” and biotic, a word associated with the Greek bios, meaning “life.” The related noun abiosis was likewise formed from Greek elements referring to the absence of life. The prefix and root also appear in words such as biology, while abiotic preserves the contrast with the life-related sense of biotic.
How abiotically is actually used
This is a specialized scientific term, especially common in ecology, geology, biology, and planetary science. It is more precise than simply saying “without biology,” since it specifically invokes nonliving environmental factors or processes.
Easily confused with abiotically
Abiotically describes a process or condition that does not depend on living organisms, whereas biologically describes one involving life or living organisms.
