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?
- Predation
- Amensalism
- Commensalism
- Competition
The Correct Option is A
Solution and Explanation
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 (-/-).

Organisms and Populations
Organisms:
An attached living system that lives in an environment is commonly known as an organism. These organisms are able to retain certain behaviors and structures. Some examples of organisms are plants, animals, bacteria, fungi, and humans. A group of these organisms leads to the formation of a population. The collection of the population forms a community that assists in the operation of ecosystems.
Each and every organism has the ability to adapt itself to various conditions of the environment. This capacity of organisms is due to their genetic variations. It is due to this only that their probability of survival get increases. For instance, camels adapt themselves to survive in desert areas and polar bears adapt to the extreme cold conditions or situations through their dense fur coat.
Populations:
A collection of organisms or individuals of a species that live, at a specific time, in a geographical area that is well-defined and capable of interbreeding is described as a population.
