Abiotic Elements That Affect Our Water. Water Chemistry. Healthy aquatic ecosystems depend upon many factors. One important factor is the chemical balance present in the ecosystem.. Aquatic ecosystems are susceptible to many chemical changes. Usually if the chemistry of a “healthy” ecosystem changes, signs of this change will include sensitive organisms quickly declining in number or disappearing. These types of organisms are called .

Methylation. is how mercury changes into organic forms and this happens under water.. Introduction. The information our group researched is important because it tells us whether terrestrial or aquatic organisms have more mercury. Mercury can also kill many people. According to the EPA, mercury can be found in air, water and soil. Mercury is everywhere and it gets there by emissions from vehicles and emissions from factories, but the main ways are through .
