Answer:A) Nitrogen
Explanation: nitrogen cycle ensures the movement of nutrients through the biosphere.it ensures that nitrogen is constantly reused and made available.
Nitrogen gas is available in the atmosphere but plants and animals cannot use it in that form.it must be converted to compounds such as ammonia or nitrate.
It is gotten from the atmosphere during rainfalls where it Is broken down and combines with oxygen to from nitrogen peroxide.
Nitrogen can also be fixated into ammonia by saprophytic bacteria.
Also when plants die their body tissues are broken down to form ammonia.ammonia can be oxidized into nitrates and nitrite which plants can use.
Nitrites can be released back into the atmosphere through denitrifying bacteria and the cycle continues.

This injury is fatal because, The phrenic nerve regulates breathing and operates the diaphragm.
<u>Explanation:</u>
The motor ability is provided by the Nerve called Phrenic nerve to the diaphragm. This is a muscle that is very important for the respiration to take place in human. When a damage or injury occurs to the Phrenic nerve, it may result in the paralysis of diaphragm.
When this is damages there may be difficulties in breathing and only small amount of air can be inhaled. Thus the paralysis of this nerve results in the prevention of the victim to find difficulties in respiration. Thus, the example given is fatal because, the phrenic nerve regulates breathing and operates the diaphragm.
