PATHOGEN:

A pathogen or infectious agent is a biological agent that causes disease or illness to its host. The term is most often used for agents that disrupt the normal physiology of a multicellular animal or plant. However, pathogens can infect unicellular organisms from all of the biological kingdoms.

HOLOZOIC NUTRITION:

Holozoic nutrition is a type of heterotrophic nutrition that is characterized by the internalization and internal processing of gaseous, liquids or solid food particles. Protozoa, such as amoebas, and most of the free living animals, such as humans, exhibit this type of nutrition.
