1. select 3 that apply.

major aquatic ecosystems are determined by what factors?
salinity
temperature
precipitation
hills
hydrostatic pressure

Explanation:

Salinity is the primary factor that differentiates marine and freshwater aquatic ecosystems. Temperature influences species survival, metabolic rates, and the distribution of aquatic life. Hydrostatic pressure is critical for deep aquatic ecosystems, shaping which organisms can thrive in high-pressure environments. Precipitation affects water volume but is not a defining factor for the ecosystem type itself, while hills are terrestrial landforms unrelated to aquatic ecosystem classification.

Answer:

• salinity
• temperature
• hydrostatic pressure
