The skin has only 2 layers—epidermis and dermis. Hypodermis, if that’s what you have in mind as the third, isn’t considered part of the skin.
The epidermis is a barrier to infection, trauma, and water loss (dehydration); it’s important to our social interactions; and it’s the body’s largest sense organ. The dermis provides toughness and resistance to mechanical stress; provides blood vessels that come close to the epidermis and nourish it (but don’t enter it); contains a variety of sensory receptors for touch, heat, cold, pressure, and vibration; and is an arena of immune defense in which white blood cells can rally at a site of infection and fight off intruders.

Since the transferrence is interrelated in a system called the food chain where the nutrients from plants is carried off by the first-consumers and second-consumers and so on untill the decomposers take the energy from the withered living organism and back into the system, it is mostly the transferrence of energy.
This flow of energy is present in its development and thus, the food composed by the photosynthetic autotrophs then is changed and took in by herbivores and then when omnivores or carnivores eat them it is translated into another form where it is stored in the cells used in many bodily activities.
The ecosystem fails and it leads to certain species dying out due to lack of enough food
