How do organisms respond to oxygen stress caused by decaying plant material?

Organisms respond to oxygen stress, which is often caused by the decomposition of plant material, primarily through experiencing reduced metabolic functions. This happens because the decay process consumes oxygen and can lead to hypoxic or anoxic conditions, making it difficult for many aquatic organisms to sustain normal metabolic rates.

In such environments, aerobic organisms, which rely on oxygen for respiration, may struggle to perform essential functions necessary for their survival and reproduction. As oxygen levels decrease, their ability to generate energy through aerobic respiration diminishes, forcing them to rely on anaerobic pathways, which are less efficient and can lead to the accumulation of harmful byproducts.

In contrast, while some organisms may find nutrient boosts due to decaying plant material, the stress caused by low oxygen typically outweighs these benefits. Rapid reproduction or migration can occur in some contexts; however, these responses are usually not the primary way organisms cope with acute oxygen stress but rather part of a broader adaptive strategy in varied environmental conditions.
