2. Sunlight and Aquatic Biomes
Photic = Light
Photic zones – Zones where sunlight penetrates the water, Where aquatic producers live
Aphotic zones – No light penetrates these zones because it is too deep, no producers
Which zone supports the most biotic factors?

3. Salinity and Temperature
Salinity – Amount of salt in the water
Temperature – decreases as you go deeper into the ocean

4. Types of Aquatic Biomes
Saltwater – Ocean biome
Freshwater – Lakes, Ponds, Rivers, Streams
Estuary – Where rivers flow into the ocean, Contains brackish water = mixture of salt and freshwater.

14. Wildlife Corridor
A bridge or tunnel that connects two forests that are separated by a roadway or other barrier.
