<span>Conservation strategies that set aside ecosystems for preservation </span>are the best way to preserve an area's diversity.
The World Wildlife Fund says that the conservation strategies that focus on ecosystems for preservation have an impact on preserving and area's diversity because it is a complete, healthy ecosystem, filled with all that is part of it, that will maintain the diversity of its area - for example, if a species of a tree from a certain ecosystem was to be extinct, not only that species would disappear, reducing already by itself the diversity of the area, but it would also affect other species taking them probably also to eventual extinction, once more reducing the diversity of the area.

Sharks are cartilaginous fishes that lives in the ocean. Oceans are always salty, hence organisms need to maintain a salt-water balance between their internal and external environment because of osmosis. Sharks are able to maintain this by ensuring that the amount of solutes in their internal environment is as much as that in their external environment.
Sharks retain a chemical contained in urine called UREA in their bloodstream to counter the osmotic effect of the salt concentration in the waters they live. This helps them maintain a concentration balance with their environment.
