The information that may be shown in an ecological pyramid is the relative amount of energy.

Mid-ocean ridges are a large, seismically activated submarine elevation system located in the center of the basin of an ocean and considering the situation of the up-welling of magma connected with seafloor expanding. Thus they are as thick as 6 Km at the mid-ocean ridges.
