Question

in which type of relationship does one organism benefit by harming the other?
a) macroorganism
b) microorganism
c) symbiotic
d) pathogenic

Explanation:

• A macroorganism is an organism that is large enough to be seen with the naked eye. It is not a type of relationship.
• A microorganism is an organism that is too small to be seen with the naked eye. It is not a type of relationship.
• A symbiotic relationship is a relationship between two organisms where at least one organism benefits. There are different types of symbiotic relationships: mutualism (both benefit), commensalism (one benefits and the other is not affected), and parasitism (one benefits and the other is harmed). Pathogenic relationships are a subset of parasitism where the parasite is a pathogen (causes disease).
• A pathogenic relationship is a type of relationship where one organism (the pathogen) benefits by harming the other organism (the host).

Answer:

D. Pathogenic
