Aquatic chemistry plays a crucial role in nutrient cycling in water environments. Chemical factors control how organisms interact with their surroundings and each other. Nutrients, like ions and gases, affect primary production and can lead to nutrient pollution. Redox potential and oxygen levels also impact chemical processes and the types of organisms that can thrive in aquatic ecosystems. Respiration rates are influenced by carbon, temperature, and nutrient availability. Understanding these chemical aspects is key to managing nutrient cycling and pollution in water environments.
