The term "biogenic" refers to substances or materials that are produced by living organisms. This can include organic matter such as plant debris, animal waste, and microbial byproducts. Biogenic materials play a crucial role in ecosystems, contributing to soil fertility and nutrient cycling. In addition to natural processes, biogenic substances can also be harnessed for various applications. For example, biogenic methane is a renewable energy source generated from the decomposition of organic matter. Understanding biogenic processes is essential for fields like ecology and environmental science, as they help in managing resources and addressing environmental challenges.
