Question

Quizplus · Accepted Answer

Estuaries are characterized by high nutrient availability due to the mixing of river and sea water, which brings nutrients from both sources. This nutrient-rich environment supports high levels of production. The constant movement of water, due to tides and river flow, helps distribute nutrients and oxygen, further supporting diverse and productive ecosystems.
