Ocean Zones
• Life zones in the ocean are determined by the depth to which light can penetrate• How is life connected to availability to light?

Photosynthesis and Nutrients
• Photosynthesis is the process by which plants use
water plus carbon dioxide and energy from the
sun to make food.
• Photosynthesis NEEDS the sun to happen
• Many animals eat plants, these animals can only
live where plants live

The Zones of the Ocean
1. Sunlight Zone: the part of the ocean that extends from the surface to about 200 meters
• This is the only part of the open ocean that receives enough sunlight to support the growth of algae• Algae are the base food of open-ocean food webs• Animals that feed on algae: krill, young crabs, mollusks,
fish

Zone of the Ocean #2
2. Twilight Zone: the part of the ocean that extends from the bottom of the sunlight zone to about 1km.
•This water is darker and colder than the sunlight zone. Why?

Zones of the Ocean #33. Dark Zone: the part of the ocean that extends from about 1km or from the bottom of the twilight zone to the ocean floor.
•Darker and colder than the twilight zone•Harsh conditions, few organisms live here•Some animals use bioluminescence to help find food• Bioluminescence – making their own light!

Bell Work:1.Complete Survey, do NOT write your name on it
![Page 12: Unit 2.5: Marine Life. Bell Work Nov 6 Agenda: 1.Planner: Choose your animal for the Oceans Animal Project by Nov 10 2.Bell Work 3.Good Things 4.Notes](https://reader036.vdocument.in/reader036/viewer/2022062800/56649e045503460f94af0018/html5/thumbnails/12.jpg)
Classification of Life in the Ocean
• Scientists classify marine organisms according to where they live and how they move. • Plankton: are tiny algae and animals that float in
the water and are carried by waves and currents• Algae (Plant) Plankton: need photosynthesis to make
their own food• Animal plankton (Zooplankton): microscopic crustaceans,
and some tiny young fish
![Page 13: Unit 2.5: Marine Life. Bell Work Nov 6 Agenda: 1.Planner: Choose your animal for the Oceans Animal Project by Nov 10 2.Bell Work 3.Good Things 4.Notes](https://reader036.vdocument.in/reader036/viewer/2022062800/56649e045503460f94af0018/html5/thumbnails/13.jpg)
Nekton
• Free- swimming animals that can move throughout the water column• Squid, most fish, and marine mammals such as
whales and seals

Benthos
• Organisms that inhabit the ocean floor• Crabs, sea stars, octopi, lobsters• Sponges, sea anemones
![Page 15: Unit 2.5: Marine Life. Bell Work Nov 6 Agenda: 1.Planner: Choose your animal for the Oceans Animal Project by Nov 10 2.Bell Work 3.Good Things 4.Notes](https://reader036.vdocument.in/reader036/viewer/2022062800/56649e045503460f94af0018/html5/thumbnails/15.jpg)
Food Chain• Algae Plankton is at the bottom of the
food chain- uses sun to make food during photosynthesis• These are called Producers
• Everything else is a consumer• They consume other organisms to
get food
• Zooplankton and some benthos eat algae plankton
• Decomposers: some organisms break down wastes ant the remains of other organism
