The ocean is very big.

Ocean Ecosystem
By: Luke Summers

What are plankton?
Plankton are small microscopic organisms that drift in the sea. Many animals feed on plankton.
How do animals change and adapt?
An octopus can change its color and skin tone to
blend into its environment.
The ocean consists of living and non-living things.
The non-living things are water, salt, gases, rocks, shells, and sometimes oil and trash.
The ocean is divided into 5 zones.
The Sunlight Zone
The Twilight Zone
The Midnight Zone
The Abyss
The Trenches
The marine ecosystem is the largest in the world. It covers 70% of the earth.
Living organisms of the sea
Here's the very popular dolphin.
Thousands of jellyfish cruising the vast ocean.
Tuna are known for their speed and agility in the water.
This is an octupus, which has very cool camouflage.

This is some colorful coral.
I'm a sea turtle!!
Sea kelp is home to many living creatures.
A lot of the living things in the ocean are so small, we can't see them without a microscope.
Animals in the ocean compete for food.
This process forms the marine food chain.
All living things in the ocean depend on
water and sunlight!
Water and Sunlight
Living and nonliving organisms depend on each other for survival in the ocean.

Hermit Crabs use shells as their home and protection.
The sun helps the plants grow which is food for many animals!
This Cuttlefish uses camouflage to hide from predators and sneak up on its prey.
Humans need to help, not harm!
Humans are changing the ocean ecosystem by
polluting the water.
Flying Fish
Flying fish live in all of the oceans.
The Sunlight Zone gets the most light because it's on the top. Many plants and animals live here.
The Twilight Zone is further from the surface and gets less light. Fewer plants and animals live here.
The Midnight Zone gets no light and very few living things can survive here. Some animals have adapted to this dark environment.
These fish create their own light and are able to survive in the deepest zones in the ocean.
Bioluminescent Fish
Like this tiny plankton.
There is a growing pile of garbage in the Pacific Ocean that is bigger than the state of Texas.
The Ocean is an amazing Ecosystem
We all need to do our part to keep the ocean clean so the marine life is not harmed.
