Question
Which of these environmental factor(s) is(are) the key determining factor(s) that control(s) the biotic structure of aquatic biomes?Question 25Select one:a.Average annual air temperature and precipitation.b.Seasonal fluctuation of water temperature.c.Oxygen concentrations and nutrient levels.d.Salinity.
Solution
The key determining factors that control the biotic structure of aquatic biomes are oxygen concentrations and nutrient levels. This is because all aquatic organisms require certain levels of oxygen to survive. The amount of oxygen in water can vary depending on temperature, salinity, and pressure. Nutrient levels, such as nitrogen and phosphorus, also play a crucial role in determining the types of organisms that can survive in an aquatic biome. These nutrients are essential for growth and reproduction. Therefore, the correct answer is c. Oxygen concentrations and nutrient levels.
