Question

organisms of two different species interact. one organism is not significantly affected, while the other benefits.
which of the following describe this interaction? select all that apply.
commensal relationship
mutualistic relationship
parasitic relationship
symbiotic relationship

Explanation:

• A commensal relationship is defined as an interaction where one organism benefits and the other is not significantly affected.
• A symbiotic relationship is a broad term that includes commensalism, mutualism (where both benefit), and parasitism (where one benefits and the other is harmed). Since the description fits within the umbrella of symbiotic relationships (as it's a type of close - long term interaction between species), it also applies.
• A mutualistic relationship requires both organisms to benefit, which is not the case here.
• A parasitic relationship has one organism benefiting at the expense (harm) of the other, which is not the situation described.

Answer:

commensal relationship, symbiotic relationship
