#Unit 10. Ecological Principles

Upwelling zones (where nutrients reach the surface from deeper waters) and continental shelf areas (where bottom sediments in shallow water rapidly exchange nutrients with surface waters) support greater production.
Freshwater production is highest in rivers, shallow lakes, and ponds, where nutrients are most abundant, and lowest in clear streams and deep lakes.
