Open oceans exhibit low photosynthetic productivity due to nutrient limitations
the verdict
SUPPORTED
the evidence backs this
confidence 80/100
Open ocean productivity is widely constrained by the availability of key macronutrients and micronutrients, establishing nutrient limitation as a fundamental driver of marine biological activity.
