Which process describes the incorporation of phosphates into organic molecules in aquatic plants and animals?

Consider the options: Reduction, oxidation, hydrolysis, and condensation are all chemical processes that can involve phosphates.

Analyze each option: Reduction and oxidation typically involve electron transfer, not the addition of phosphate groups. Hydrolysis involves breaking bonds with water, which is not directly about adding phosphates. Condensation involves joining molecules together, often with the release of a small molecule like water, which can include the formation of phosphate esters.
