In the Marine Ecosystem is where we will find our oceans and where we will find marine life and plants.
The marine ecosystem covers most of the earth’s surface and there are millions of different plants and animals in the marine ecosystem.
There are five oceans around the world; Arctic, Atlantic, Indian, Pacific and Southern oceans and they all have water.
These oceans cover over 70% of the earths surface and one of the deepest oceans, Mariana Trench is as deep as Mt. Everest is tall.
In the ocean and the saltwater bays, in seas and in inlets, there are small organisms and bacteria that help make up part of the creatures that live in the Marine Ecosystem.
There are three zones in the ocean, the euphotic zone, this zone gets the most sunlight, the disphotic zone, this zone gets some sunlight but not enough for plants to survive and the third zone, the aphotic zone, gets no sunlight at all.
Plant life in the ocean gets food from photosynthesis so the top zone is the only zone that has plants.
These plants include seaweed, sea grasses and algae. Kelp is one plant that is known to grow in the ocean.
Plankton and other fish are found in the ocean. Plankton is a huge source of food to marine life.
There are other animals such as fish, walruses, whales, bacteria, seals, dolphins and so many more. There are animals found in the ocean that even make their own light.
The ocean is so big that no one is sure that all the animals in the ocean have been discovered and new discoveries are happening all the time.
Since the ocean gets super deep, most of the animals live in the top 200 meters of the water and the ocean that is deep is very dark and there is very little food.
