biogênic

Biogenic refers to something originating from or produced by living organisms. This term is commonly used in various scientific fields, including biology, geology, and chemistry, to describe substances, processes, or materials that have a biological origin. For instance, biogenic elements are essential nutrients required for life, such as carbon, nitrogen, and phosphorus, which are cycled through ecosystems by living organisms.

In geology, biogenic sediments are formed from the accumulation of organic remains, such as shells, skeletons, and plant matter. Examples include limestone, chalk, and coal, all of which are direct or indirect products of biological activity over geological timescales. Biogenic rocks are distinct from abiogenic rocks, which form through purely physical or chemical processes.

The concept of biogenic processes also extends to the creation of complex molecules. Many organic compounds essential for life are synthesized by living cells through metabolic pathways. Furthermore, the term can describe environmental influences. For example, biogenic amines are organic compounds derived from amino acids and play crucial roles as neurotransmitters and in various physiological functions within organisms. Understanding biogenic origins helps scientists trace the history of life, analyze geological formations, and comprehend biochemical processes.
