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 . Single-celled organisms. Very tiny. Cannot be seen without a microscope. Our microscopes are not powerful enough. Lack a nucleus and most other organelles. Most numerous organisms on Earth. Extremely important organisms.. Aquatic ecosystems are primarily determined by the ecosystem’s . salinity. . Salinity refers to the dissolved salt content of the water.. Aquatic ecosystems are divided into freshwater and marine ecosystems.. methylation. . . 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 . Basic Chemical Properties of Nickel. This metal doesn’t oxidize very quickly. There are a few common oxidation states. +2 Ni, +1 Ni, and +3 Ni. The most common:+2 Ni. Basic Physical Properties of Nickel. Homeostasis. 2. Homeostasis. is the way an organism maintains a stable internal environment within itself. Body systems coordinate their activities to maintain homeostasis.. This is done through the use of positive and negative feedback loops . Topography dictates water flow.
