Question

What does the term endosymbiosis mean? a When one organism uses another one for nutrients b When two organisms compete for resources c When one organism lives inside another and they both benefit d When one organism consumes another organism and digests it

Answer 1

c) When one organism lives inside another, and they both benefit.

Step-by-step explanation:

Endosymbiosis is a biological relationship in which one organism (the endosymbiont) lives inside another organism (the host) and both organisms benefit from the association. This type of symbiotic relationship can be mutualistic, meaning both the host and the endosymbiont gain advantages from the interaction. An example of endosymbiosis is the relationship between mitochondria and eukaryotic cells. Mitochondria are thought to have originated as free-living bacteria that were engulfed by ancestral eukaryotic cells and eventually became a permanent part of the cell, providing energy production through respiration.
