Read the following statements regarding the symbolic representation of population interactions, where (+) denotes a beneficial interaction, (-) denotes a detrimental interaction, and (0) denotes a neutral interaction. Which of the following statements is incorrect?

Options

  1. AIn amensalism, one species is harmed whereas the other is unaffected, which is represented by a (-, 0) sign co
  2. BBoth predation and parasitism are assigned a (+, -) sign convention because in both cases only one species ben
  3. CCommensalism is represented by (+, 0) since one interacting species derives a benefit while the other remains
  4. DCompetition is represented by a (+, -) sign convention because the competitively superior species benefits whi

Correct answer

D. Competition is represented by a (+, -) sign convention because the competitively superior species benefits whi

Step-by-step solution

In population interactions, competition is defined as a process in which the fitness of one species is significantly lower in the presence of another species. It is detrimental to both species involved, regardless of which species is competitively superior. Therefore, competition is represented by a (-, -) sign convention, not (+, -) . The other statements are correct: Amensalism is (-, 0) as one species is harmed and the other is unaffected. Predation and parasitism are both (+, -) because one species benefits at
