a. aristotle
b. columella
c. freud

b. Columella

Explanation:

The professional who dedicates himself to the care of animal health has, throughout history, received different names, of which we highlight mulomedicus, mariscal, maréchal, farrier, albeytar, alveitar, hipologist and veterinarian.

There is no unanimity as to the origin of the term "veterinarian". For some, it derives from veterinarius, the chief shepherd of the clan, from the Latin spirit veteranus (from vetus, old man); for others, de vehere, which in vulgar Latin means to bring (de vehe, vehicle); there are also those who associate it with a veterinarian (donkey) or veterinus (pack or draft animal).

The Roman author Columela is considered the first to use both the term veterinary medicine, to designate the art of healing horses and other beasts, and the name veterinarius, to the person in charge of this function.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
