Which of the following factors is not associated with aquatic habitats?

Edaphic is the factor that is not associated with aquatic habitats. This term refers to the study of soil characteristics and their relationship with plants, but it has no relevance to aquatic environments. Aquatic habitats are characterized by specific physical and chemical factors that are different from those of terrestrial habitats. Salinity is the concentration of dissolved salts in water, which affects the types of organisms that can survive in it. Turbidity is a measure of the clarity of water and is affected by the presence of suspended particles. Temperature is a critical factor that influences the metabolic rates and distribution of aquatic organisms. In summary, edaphic is not associated with aquatic habitats because it is a term that relates to soil characteristics and not water.
