Answer:
In biology, the relationship in which one organism lives inside another is described by the term endosymbiosis.
Explanation:
Endosymbiosis refers to a form of association that organisms have, in which one individual lives and performs his functions within another's body -using his resources to survive- being called the first symbiont, and the second host.
An example of endosymbiosis is found in bacteria that are part of the intestine of some living organisms, contributing to the process of food degradation.
Additionally, endosymbiosis is relevant in explaining the origin of eukaryotic cells from symbiosis between prokaryotic cells, which is known as endosymbiotic theory.
