Question

Symbiosis is an interaction between two species in which ________.

• A. Both live together in direct contact
• B. Both benefit
• C. One benefits and the other is neither helped nor harmed
• D. One benefits and the other is harmed

Answer 1

Answer: (B)

Both benefit

In a symbiotic relationship, the two species in the relationship live together. Many organisms are involved in symbiotic relationships because this interaction provides benefits to both species. Symbiotic relationships can be obligate or facultative. Obligate symbiosis is when two organisms are in a symbiotic relationship because they can't survive without each other. Facultative symbiosis is when the species live together by choice. There are four main types of symbiotic relationships: mutualism, commensalism, parasitism, and competition.

So, the correct answer is option B.
