- From what investigators do know, it is clear that marine animals display a greater diversity of body types than land animals do.
- total estimates run closer to 400,000 to 450,000.
- Seawater is about 800 times as dense as air and is much more viscous.
- Life underwater has a unique hue as well. Water absorbs light differently than air does.
- This rain of plant food is hardly constant, however. Phytoplankton are seasonal and vary by region.
- smaller species—called prochlorophytes—are found in tropical and mid-ocean waters.
- Temperature and depth also play an important role because these variables control the availability of oxygen.
- On land, air provides plants and animals with a fairly constant mixture of this life-giving gas: 210 milliliters per liter. In the sea, oxygen enters only at or near the surface.
- Recent studies of the deep sea suggest that although the diversity of species is high, their density is quite low.
- Food for these organisms arrives in the unending shower of organic particles called marine snow—although sometimes a large carcass, a clump of kelp or a waterlogged tree may settle on the seafloor.
- Human actions have also profoundly affected many coral ecosystems.
The Articles implies to how human actions are affecting many coral ecosystem. Life is the ocean has been very mysterious. Researches tried to find out whats going on in under worlds. Small species called prochlorophytes are found in tropical and mid-ocean. Seawater is about 800 times as dense as air and is much more viscous. The ocean does not contain much plant life. Only 250,000 species has been identified; total estimates run closer to 400,00 o 450,00. The marine have been left out of saving biodiversity.
After reading this articles, I learned that the species underworld is decreasing and dying because of humans actions. Humans cant protect the life of the ocean because others doesnt care. And others thinks its not our fault that we are causing them to die. Human population grows while the animals and plants decrease. This can be a really big problem and we should do something about this.
