Document Summary
Chlorophyll in phytoplankton can remove co2 in atmosphere, changing climate. *final: negatively charged colloids are the force, which hold ions in soil. In most cases, chlorophyll concentration varies from low to mid. Chlorophyll is the molecule that does photosynthesis, so oceans can also contribute to fixing carbon and making sugars. Water, mostly salt water in oceans, covers majority of earth"s surface. Oceans influence global climate because it can control global temperature . Chlorophyll also contributes to biodiversity in ocean phytoplankton can be eaten. The oceans contain more than water 96. 5% water. There are also nutrients nitrogen (plants inside the salty water), phosphorus. Dissolved gas oxygen added by plants, bacteria, and atmospheric diffusion. The rest, 3. 5% is mostly salt and other minerals. Out of those 3. 5%, 3% goes to sulfate (0. 3%), chloride (2%) and sodium (1. 1%) by many larger organisms, therefore there is high biodiversity in salty waters. Also use oceans for transportation and commerce happens.
