Aquatic biome light-redox carbon cycling

Aquatic biomes are structured by water bodies that partition microbial life into illuminated photic water, sinking particulate organic matter, dissolved organic substrates, and redox gradients. Oxygenic phototrophs fix carbon in the photic zone, heterotrophic bacteria hydrolyze and respire that organic matter, and oxygen depletion enables anaerobic redox metabolisms that recycle nutrients.
