If we assign a '+' sign to represent beneficial interactions, a '-' sign to represent detrimental interactions, and a '0' sign to represent neutral interactions, then the population interaction represented by a '+' '-' refers to what?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) - Parasitism
In parasitism, one species (the parasite) benefits from the interaction, while the other species (the host) is harmed. This is represented by the + and - signs, respectively.
Mutualism is a type of interaction in which both species benefit.
Commensalism is a type of interaction in which one species benefits, while the other species is neither harmed nor benefited.
Amensalism is a type of interaction in which one species is harmed, while the other species is unaffected.
Therefore, the population interaction represented by (+) (-) refers to parasitism.
