which is one quality of the entire open - ocean zone?\no few nutrients\no low pressure\no ample sunlight

Answer:

A. few nutrients

Brief Explanations:

The open - ocean zone generally has few nutrients as most nutrients sink to the ocean floor or are concentrated near the shore. Pressure increases with depth in the ocean, so it's not low - pressure throughout. Sunlight only penetrates the upper layers, not the entire open - ocean zone.
