Answer:
At least one member must benefit in a symbiotic relationship.
Explanation:
Symbiosis generally refers to the interaction between two species of organisms that live closely together in the same environment. In symbiosis, different scenarios can play out, they are:
both organisms can benefits from the relationship i.e. mutualism
only one organism could benefit from the relationship, while causing harm to the other i.e. parasitism
only one organism benefits from the relationship, but no harm or damaged is caused to the other organism. i.e. commensalism.
From the above three scenarios highlighted above, we can see that at least, one member must benefit in the symbiotic relationship.
Invariably, among the statements given in the question, "At least one member must benefit in a symbiotic relationship" is the only statement that is TRUE.
