Organisms use nitrogen in which one of the following ways?

Hello. You did not enter the options, but the organisms use nitrogen in the following ways:

Explanation:

Nitrogen is an essential chemical element for the existence of life on Earth, since it is a component of all the amino acids in our body, components of the nitrogenous bases that make up the DNA and RNA molecules, a component of proteins, in addition to allowing the growth of vegetables that will serve as food for other living beings. Approximately 78% of the air we breathe is composed of nitrogen from the atmosphere (N2), which is its largest reservoir.

Despite this, few living beings have the ability to absorb it in its molecular form (N2). It turns out that nitrogen, like iron and sulfur, participates in a natural cycle during which its chemical structure undergoes transformations in each of the stages, serving as a basis for other reactions and thus becoming available to other organisms - this being great importance of the nitrogen cycle (or "nitrogen cycle").

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
