Ocean Life Zones

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

Ocean life is determined by many factors: B: Temperature – most animals live near the surface where it is warmer

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

Animals and plants can be classified into three major groups A: Plankton – very small animals that float on or near the surface

Animals and plants can be classified into three major groups B: Nekton – animals that can swim with their own power

Animals and plants can be classified into three major groups C: Benthos – animals that live on the ocean floor

List and describe the major ocean life zones A: Intertidal – lies between the low and high tide lines

List and describe the major ocean life zones B: Sunlight – Extends from the low tide line to the continental shelf

List and describe the major ocean life zones C: Open Ocean is divided into two areas 1. Twilight 2. Midnight

Create a foldable Fold in half hotdog style 1 inch from the edge Fold in half and in half again to make 4 sections Intertidal Sunlight Photic Zone Twilight Ocean Midnight Aphotic zone

Create a foldable Label and color each section Intertidal Sunlight Photic Zone Twilight Ocean Midnight Aphotic zone

Cut between each color to make four flaps Turn your foldable so you can write on the white strip Intertidal Sunlight Photic Zone Twilight Ocean Midnight Aphotic zone Intertidal Between low and high tides

Cut between each color to make four flaps Turn your foldable so you can write on the white strip Intertidal Sunlight Photic Zone Twilight Ocean Midnight Aphotic zone Sunlight Low tide to the edge of the continental shelf

Cut between each color to make four flaps Turn your foldable so you can write on the white strip Intertidal Sunlight Photic Zone Twilight Ocean Midnight Aphotic zone Open Ocean- Continental shelf down to about 2000 m

Cut between each color to make four flaps Turn your foldable so you can write on the white strip Intertidal Sunlight Photic Zone Twilight Ocean Midnight Aphotic zone Midnight Deepest parts of the ocean down to 7 miles

Open the intertidal flap and write on the left hand side Sunlight Photic Zone Twilight Ocean Midnight Aphotic zone Half the day it is underwater, the other half it is dry. These are the estuaries.

Open the Sunlight flap and write on the left hand side Intertidal Sunlight Photic Zone Twilight Ocean Midnight Aphotic zone Coastal shoreline. Presence of light and photosynthesis means most life located here.

Open the Open ocean flap and write on the left hand side Twilight Ocean Intertidal Sunlight Photic Zone Twilight Ocean Midnight Aphotic zone Very little sunlight, temperatures right above freezing. Diversity of life decreases the deeper you go.

Open the Midnight ocean flap and write on the left hand side Intertidal Sunlight Photic Zone Twilight Ocean Midnight Aphotic zone Bottom of the ocean. No sunlight, freezing temperatures, few nutrients. Most life is chemo-synthetic.

Color each section the following color Intertidal Color each section the following color Sunlight Photic Zone Twilight Ocean Midnight Aphotic zone
