In an intertidal zone, air and currents are strong. Animals that live in these areas should deal with these environments. One characteristics of these animals that help them survive is their tube feet. With this, they can secure themselves to rocks. In order to deal with sun, snails and oysters forms a seal around their shells.
Animals that live in the intertidal zone have to deal with exposure to air, as well as strong currents. Many organisms such as sea stars or sea urchins have developed what are called tube feet. Tube feet help to secure them to their rock. So some form of anchoring themselves. To deal with sun exposure, snails such as periwinkles and oyster drills . This forms a watertight seal around the <span>shell, protecting them from the sun. So here, it would be moisture control.</span>
A forest ecosystem can support a limited number of bears. This is because available energy is lost from one trophic level to the next. (flies, trout, then bears)
Active transport refers to the natural movement of molecules across a cell membrane from lower concentrations to higher concentrations. This cellular mechanism has the role to reduce the differences in the concentrations of these molecules
The physiology of stress has two components. One in which is a fast response meditated by the SAM axis, and one which is a slow response meditated by the HPA axis.
