Which of the following symbiotic relationships are WIN - Zero?

Group of answer choices

Commensalism

Mutualism

Parasitism

Commensalism.

In a WIN-Zero symbiotic relationship, one organism benefits while the other is unaffected (zero impact). Among the given options:

1) Commensalism: In commensalism, one organism benefits while the other is neither harmed nor benefited. This relationship does not fit the criteria of WIN-Zero, as there is no need for one organism to be unaffected.

2) Mutualism: In mutualism, both organisms benefit from the relationship. This relationship does not fit the criteria of WIN-Zero, as both organisms experience positive effects.

3) Parasitism: In parasitism, one organism benefits (parasite) while the other organism is harmed (host). This relationship does not fit the criteria of WIN-Zero, as one organism is negatively impacted.

Therefore, none of the given symbiotic relationships (commensalism, mutualism, and parasitism) are considered WIN-Zero relationships.
