list all the abiotic factors existing in the ecosystem of aquatic ecosystem
Answers
Answer:
Abiotic factors are components of a natural environment that are not alive. In other words, physical or chemical parts of the environment that affect the organisms that are in that environment. For aquatic ecosystems, these factors include light levels, water flow rate, temperature, dissolved oxygen, acidity (pH), salinity and depth.
Light level is an important factor in aquatic ecosystems. Light is needed by plants for photosynthesis, the process where plants turn light into energy. Light can affect the success of predators at finding food, and directly affects how much life you find in a given area. In fact, when swimming and diving tourists stir up sediment as they explore, they can damage shallow water ecosystems simply by reducing the amount of light that reaches them.
Another important factor is the water flow rate. Many organisms can only survive at certain water flow rates, and struggle when rates are too high or too low. The flow of water is responsible for moving oxygen into some organisms' gills, and even helps food like plankton flow into the mouths of other aquatic animals.
Temperature is just as important for aquatic ecosystems as it is for land animals. Just like how humans don't operate as well when they are too cold or too hot, the metabolic rate of organisms under water is also affected by temperature. This is because organisms are adapted to survive in specific temperature ranges.
Oxygen content in water is something humans don't think about much because we can't breathe underwater.
