Hypoxia: A condition where dissolved oxygen levels in water are low, often leading to dead zones where aquatic life cannot survive.

Eutrophication:

The process by which water bodies become enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Biogeochemical cycles: Natural processes that recycle nutrients in various chemical forms from the environment to living organisms and back again.
