Marine Ecosystems

Zones of Marine ecosystems• 2 Main Divisions Based on Light

– Photic• 200 m• photosynthesis

– Aphotic• Permanent darkness• chemosynthesis

• Depth/Distance Divisions– Intertidal Zone

• Rocky• zonation

– Coastal Ocean• Low tide mark to outer edge of

continental shelf– Open Ocean

• Edge of continental shelf and outward• 500m to 11000m• Largest division
