Understand the concept of commensalism: Commensalism is a type of symbiotic relationship where one species benefits from the interaction, while the other species is neither helped nor harmed.
Compare commensalism with other types of symbiotic relationships: Mutualism involves both species benefiting, parasitism involves one species benefiting at the expense of the other, and competition involves both species being harmed.
Analyze the options provided in the question: Identify which option aligns with the definition of commensalism.
Eliminate incorrect options: Remove options that describe mutualism, parasitism, or competition, as they do not match the definition of commensalism.
Select the correct answer: Choose the option that states 'One species benefits while the other is neither helped nor harmed,' as this best describes commensalism.
