I. Water is another the most important factor influencing the life of organisms.
II. The salt concentrations (measused or salinity in parts per-thousand) is less than 15 in inland waters, \(60-65\) in the sea and \(>\) 100 in some hypersaline lagoons.
III. Many animals use the diurnal and seasonal variations in light intensity and duration as cues for timing their foraging, reproductive and migratory activities.
