    1,155 words
    An ecosystem is the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space. The principles underlying the study of ecosystems are based on the view that all the elements of a life-supporting environment of any size, whether natural or man-made, are parts of an integral network in which each element interacts directly or indirectly with all others and affects the function of the whole. All ecosystems are contained within the largest...

  • Organic Molecules Organic Matter
    633 words
    Dissolved oxygen infers to the volume of oxygen that is contained in water. Oxygen enters water through photosynthesis and across the water interface. The amount of oxygen that can be held by the water depends on the water pressure, salinity, and temperature. Gas solubility increases with decreasing temperature; thus colder water holds more oxygen. A reason why freshwater holds more oxygen than does saltwater is because gas solubility increases with decreasing salinity. When there is a change in...
