What is the advantage of a closed circulatory system over an open one?

Most of the vertebrates have the closed circulatory system inside there body to supply the sufficient amount of materials by using more efficient mechanisms having less loss of the nutrients during the supply of these materials or molecules to the different cells and tissues.While the closed circulatory system is more efficient and uses less amount of medium for the transportation of the materials to the different tissues and cells.However, the open circulatory system is found inside the invertebrates having the mechanism of bathing of the different cells and tissues inside the organism's body, this requires too much amount of medium for the transportation of the nutrients and minerals, and that is too very inefficient in nature as compared to the closed form of circulatory system.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          

The answer is magnitude measures the effects of an earthquake on the area , while the intensity measures the strength of an earthquake.
