biogenic
Made by creatures
Biogenic means produced by living organisms or biological processes.
Biogenic compounds include substances like methane from decomposing organic matter, oils from plants, or minerals formed by shellfish.
The term distinguishes naturally produced materials from synthetic or geological ones: biogenic carbon, biogenic sediments.
In environmental science, biogenic emissions refer to gases released by vegetation and other life forms.
