Neretic Zone (Plants)

• Photosynthesis  can occur.
• Warm water
• Shallow water

Neretic Zone (Animals)

• Live in coral reefs
• Travel in big groups
• Feed on algae

Surface Zone (Plants)

• Algae floats on top of the water.
• Carries out photosynthesis.

Surface Zone (Animals)

• Animals depend on algae to live.

Deep Zone (Plants)

• Plants don't grow.
• NO sunlight.

Deep Zone (Animals)
