Select the INCORRECT pair from the following:
- AMutualism - Both species are benefited
- BCommensalism - One species benefited and other is neither benefited nor harmed
- Correct answerCParasitism - Interaction is detrimental to parasite
- DCompetition - Both species are harmed
Solution
In mutualism, both species are benefited (+, +).
In commensalism, one species is benefited and the other is neither benefited nor harmed (+, 0).
In parasitism, the parasite is benefited (+) and the host is harmed (-). The interaction is detrimental to the host, not the parasite.
In competition, both species are harmed (-, -).
Therefore, the incorrect pair is Parasitism - Interaction is detrimental to parasite.
Answer: Parasitism - Interaction is detrimental to parasite
In commensalism, one species is benefited and the other is neither benefited nor harmed (+, 0).
In parasitism, the parasite is benefited (+) and the host is harmed (-). The interaction is detrimental to the host, not the parasite.
In competition, both species are harmed (-, -).
Therefore, the incorrect pair is Parasitism - Interaction is detrimental to parasite.
Answer: Parasitism - Interaction is detrimental to parasite
Hence, the correct answer is option: 'C'.
