Notes:
- Researchers have studied less than 10% of the ocean
- Marine animals have a greater diversity in body type then land animals do
- Seawater is about 800 times as dense as air
- some organisms deep sea depend on photo synthesizers for food
- Ocean has very little plant life because there isn't as much nutrients as in soil
- Temperature and depth control the amount of oxygen available.
- Only a few animals can adapt to low oxygen places
- Although there is a lot of species the density is low
- Many animals glow for protection or to identify other species
- Human activities also affect coral ecosystems
Summary
The ocean is one of the greatest mysteries in the world. Only 10% of the ocean has been studied and there are depths that no one has ever been able to see. The ocean has a high diversity of creatures and have different body types, more than land species. There different kinds of animals, some glow for different purposes like protection and creating light underwater where light doesn't reach. In the ocean plant life is much different. With very little oxygen and low levels of nutrients, plants don't grow as well as in land. Many factors can affect the availability of oxygen like temperature and depth. Although there are many different species the density is very low due to the lack of resources to support each specie.
Opinion
I think the ocean is an incredible thing. Knowing that less than 10% of the ocean has been discovered makes you wonder what mysteries are yet to be discovered. I think it's interesting that there are species that glow in the dark for specific reasons. I believe that soon we will be able to discover more depths of the ocean and more species and learn from them.
