Question

which of the following phrases describes a typical river mouth? a. clearer water with high levels of oxygen b. decreased vegetation and lower oxygen levels c. increased species diversity d. high levels of vegetation please select the best answer from the choices provided

Explanation:

River mouths are transition zones between rivers and larger water - bodies. They often have a mix of freshwater and saltwater, creating a unique habitat that supports a wide variety of species, leading to increased species diversity. Water at river mouths is usually turbid due to sediment load, not clearer with high oxygen (a is incorrect). Vegetation can be present but not necessarily at extremely high levels (d is incorrect), and there is not typically decreased vegetation and lower oxygen levels compared to other water - body areas (b is incorrect).

Answer:

C. increased species diversity
