Ocean life is determined by many
factors:
A: Sunlight –
Producers require
sunlight for
photosynthesis
Ocean life is determined by many
factors:
B: Temperature – most

Ocean life is determined by many
factors:
C: Water Pressure is
less at the surface
allowing for different

B: Nekton – animals
that can swim with

life zones
A: Intertidal – lies
between the low and
high tide lines

life zones
B: Sunlight – Extends
from the low tide line
to the continental shelf
