Answer:
The only way for gases to diffuse in and out of the leaf is though small openings on the underside of the leaf, the stomata. The stomata can open and close

Explanation:
A food chain can be described as a series of energy dilutors, the energy that fails to reach the next level being dissipated as heat or movement. Most of the energy contained in the food of animal consumers is used by them during the processes of food collection, digestion and other essential metabolic activity. The overall efficiency of a food chain is therefore rather low and depends mainly on the number of different participants and thus on the length of the food chain. Generally, the greater the complexity of the food web the greater is the efficiency of the system as a whole. The main factors that determine the efficiency of food transfer are temperature, energy, and protein supply. Proteins form the major part of digestible algal and of animal cells; animals depend on receiving an adequate supply with their food because they are unable to synthesize some amino acids.
The nurse should administer an injection of postexposure prophylaxis for tetanus. Tetanus is a toxic substance produced by a bacterium that cannot survive air (oxygen) exposure, that is why deep wounds are more vulnerable to tetanus. A moderate burn injury is considered an open dirty wound, therefore the patient should be protected from tetanus.
There is a vaccine for tetanus, that provides immunization from this disease, but it needs to be repeated every 10 years. However, in cases where there is an open dirty wound, the vaccine is believed to be inactive if it was not done within the last 5 years.
In this case, the child will not receive the tetanus vaccine, but an injection of active immunization, which acts much faster, but does not last as long as the vaccine.
