Question

While explaining interspecific interaction of population, (+) sign is assigned for beneficial interaction, (-) sign is assigned for detrimental interaction and (0) for neutral interaction. Which of the following interactions can be assigned (+) for one species and (-) for another species involved in the interaction?

• A. Predation
• B. Amensalism
• C. Commensalism
• D. Competition

Answer 1

Answer: (A)

Predation

Answer 2

When one organism benefits and the other is harmed, the interaction is called predation, and it is represented as (+/-).
Conversely, amensalism denotes a relationship in which one organism is negatively impacted while the other is unaffected and is indicated by (-/0).
Commensalism, on the other hand, describes a relationship in which one organism benefits while the other is neither helped nor harmed, and it is denoted by (+/0).
Competition occurs when both organisms are negatively affected, resulting in a representation of (-/-).
