Read the following statements regarding population interactions: (A) In amensalism, one species is harmed whereas the other is unaffected. (B) Both species lose in competition, which is represented as (-, -). (C) The association of mycorrhizae with the roots of higher plants represents a (+, 0) interaction. (D) Predation and parasitism share the same (+, -) signs for the interacting species. How many of the above sta

Step-by-step solution

Statement (A) is correct: In amensalism, one species is harmed (-) and the other is unaffected (0). Statement (B) is correct: Competition is a detrimental interaction for both interacting species, represented as (-, -). Statement (C) is incorrect: Mycorrhizae is an example of mutualism where both the fungi and the higher plants benefit, which is a (+, +) interaction, not commensalism (+, 0). Statement (D) is correct: In both predation and parasitism, one species benefits (+) at the expense of the other species whic
