Question

____ is a relationship in which both members __; __ is a relationship in which one member __, but the other organisms neither benefits or is harmed... the effect is ____. options: relationship, benefits, harmed, benefits, benefit, neutral, commensalism, mutualism, symbiotic, parasitism

Explanation:

To solve this, we analyze symbiotic relationships:

First Blank (Relationship with mutual benefit):

Mutualism is a symbiotic relationship where both members benefit. So the first term is "Mutualism", and the action for both is "benefit".

Second Blank (Relationship with one benefit, one neutral):

Commensalism is a symbiotic relationship where one member benefits, and the other is "neutral" (neither benefits nor is harmed).

Filling the Blanks:

1. [Mutualism] is a relationship in which both members [benefit].
2. [Commensalism] is a relationship in which one member [benefits], but the other organism neither benefits or is harmed… the effect is [neutral].

Answer:

First sentence: Mutualism; benefit
Second sentence: Commensalism; benefits; neutral

(Note: The word bank terms are used as follows:

• Mutualism (relationship, both benefit)
• Commensalism (relationship, one benefits, other neutral)
• "benefit" (for mutualism, plural subject "both members" → "benefit")
• "benefits" (for commensalism, singular subject "one member" → "benefits")
• "neutral" (describes the other organism’s effect) )
