Amensalism can be represented as:
- Species $A (-)$; Species $B (0)$
- Species $A(+)$; Species $B(+)$
- Species $A (-)$; Species $B (-)$
- Species $A(+) $; Species $B(0)$
The Correct Option is A
Solution and Explanation
Amensalism is an ecological interaction where one species is harmed while the other species remains unaffected. This interaction is typically represented by the symbols: Species A (-) and Species B (0).
Let’s examine the options to identify the correct representation of amensalism:
- Species A (-); Species B (0): This option aligns accurately with the definition of amensalism, where Species A is negatively affected (harmed) and Species B experiences no effect.
- Species A (+); Species B (+): This represents mutualism, where both species benefit. Hence, it does not describe amensalism.
- Species A (-); Species B (-): This represents competition, where both species are negatively affected. This is not amensalism.
- Species A (+); Species B (0): This describes commensalism, where one species benefits and the other is unaffected. It is not a representation of amensalism.
Therefore, the correct representation of amensalism is: Species A (-); Species B (0).

Population Interactions
Population interaction is generally between two different species populations.“Population interaction is the interaction between different populations. It refers to the effects that the organisms in a community have on one another.”
An ecosystem is a geographic area wherein plants, animals, and many other organisms, alongwith weather and landscape, work together to form a bubble of life.
Types of Population Interactions:
Interactions can be beneficial or neutral or detrimental. Accordingly, there are six types of population interaction.
The different ways populations interact with each other can be summarized under the following headings.
- Competition
- Predation
- Herbivory
- Mutualism
- Commensalism
- Parasitism
- Competition
