As a rule, the gill area is greater in fast-moving crabs (Portunids) than in sluggish bottom dwellers; decreases progressively from wholly aquatic, to intertidal, to land species; and is greater in young crabs than in older crabs. Often the gills are enclosed in protective chambers, and ventilation is provided by specialized appendages that create the respiratory current. As in cephalopod mollusks, oxygen utilization is relatively high—up to 70 percent of the oxygen is extracted from the water…

This is one way in which energy is transferred between organisms in an ecosystem. The energy is used for a number of life processes. In a food chain only around 10 per cent of the energy is passed on to the next level. The rest of the energy passes out of the food chain in a number of ways: 1. via heat energy 2. is used for life processes (for example movement) 3. uneaten parts that pass to decomposers 4. is excreted and passes to decomposers. As less energy is transferred at each level…
