Detailed explanation-1: -The main limiting factors in an aquatic environment are temperature, sunlight, Oxygen content, nutrient availability and salinity. So the correct answer is ‘ O2’.
Detailed explanation-2: -The amount of oxygen that can be dissolved in water depends on several factors, including: water temperature, the amount of dissolved salts present in the water (salinity), and atmospheric pressure (Tables 1 and 2).
Detailed explanation-3: -7.5 Dissolved Oxygen Oxygen has a limited solubility in water directly related to atmospheric pressure and inversely related to water temperature and salinity. Low-dissolved oxygen levels can limit the bacterial metabolism of certain organic compounds.
Detailed explanation-4: -Temperature, sunlight, oxygen content, nutrition availability, and salinity are the main limiting factors in an aquatic ecosystem.
