question 4 points 3
which of the following statements are true about commensalism?
i. commensalism is the interaction between two species.
ii. commensals neither harm nor help the other species.
iii. commensals are also called hitchhiking species.

statements i and ii
statements ii and iii
statements i and iii
statements i, ii, and iii

Explanation:

• Statement I: Commensalism is a type of symbiotic interaction involving two different species. So this is true.
• Statement II: In commensalism, one species (the commensal) benefits, and the other species is neither harmed nor helped. So this is true.
• Statement III: Commensals are often referred to as hitchhiking species as they "hitch a ride" or benefit from another species without affecting it negatively or positively (in terms of the host species' fitness in the context of the interaction). So this is also true.

Since all three statements (I, II, and III) are true about commensalism, we choose the option that includes all three.

Answer:

Statements I, II, and III
