Question

an example of an antagonistic relationship within a biological community is

o competition
o commensalism
o parasitism
o mutualism

Explanation:

Antagonistic relationships in a biological community involve one organism being harmed. In competition, organisms vie for resources and can harm each other's survival and reproduction. Commensalism is a +/0 relationship (one benefits, the other is unaffected). Parasitism is a +/ - relationship where the parasite benefits and the host is harmed, but it's a more specific type of antagonism compared to the general -/ - nature of competition. Mutualism is a +/+ relationship. Competition is a broad - based antagonistic interaction.

Answer:

A. competition
