anoxic environments

Anoxic environments are places where oxygen is absent or very low in concentration, making it difficult for most life forms to survive. These conditions often occur in deep-sea sediments, marshes, or even some underground caves. In these areas, specialized organisms, like certain bacteria, thrive by using alternative processes to generate energy. Anoxic environments play a crucial role in various ecological and geological processes, such as decomposition and nutrient cycling, and can influence the chemical composition of the surrounding water and soil.
