Abiotic Factors: Shaping Marine Life The underwater world is a fascinating tapestry of life influenced by a delicate balance of abiotic factors. Temperature Warm vs. Cold Warm waters support a greater diversity of organisms, while colder waters can be harsh, requiring specific adaptations. Adaptations Marine organisms have evolved unique mechanisms to cope with temperature fluctuations, such as migration, hibernation, or physiological adjustments. Salinity Salt Levels The amount of dissolved salts in seawater varies, impacting the distribution and survival of organisms. Estuaries These transition zones where freshwater meets saltwater are particularly challenging, requiring specialized adaptations from marine life. Osmoregulation Organisms have evolved mechanisms to maintain their internal water balance, adjusting to different salt concentrations. Nutrients Plankton Nutrient-rich waters support the growth of phytoplankton, the base of the marine food web. Fish These nutrients fuel the abundance of fish and other marine life, contributing to healthy ecosystems. Coral Reefs Nutrients support the growth of coral reefs, which provide essential habitats for countless species.
