Question

What abiotic factor of estuaries poses a risk to plants and why?

Answer 1

Temperature, Salinity.

Step-by-step explanation:

One of the most well-studied abiotic variables influencing the distribution and abundance of organisms is temperature. Since it impacts their metabolic rates and growth and reproduction rates, the temperature has a significant impact on plants and animals. Salinity is another abiotic characteristic of estuaries that endangers vegetation. As a result of the inflow of fresh water from rivers and the outflow of salt water from the ocean, estuaries have higher salinity levels than other aquatic habitats. This may result in an imbalance in the chemical makeup of the water, which would lower the concentration of vital nutrients and minerals. Because plants need these elements for survival when salinity levels are too high, the plants cannot get the sustenance they require and eventually perish.

Answer 2

One of the abiotic factors of estuaries that poses a risk to plants is salinity. Estuaries have higher salinity levels than other aquatic environments due to the influx of fresh water from rivers and the outflow of salt water from the ocean. This can cause an imbalance in the water's chemical composition, leading to a decrease in the concentration of essential nutrients and minerals in the water. Plants need these nutrients and minerals to survive, so when the salinity levels become too high, the plants will not be able to receive the necessary nourishment and will die.
