Question

Amensalism can be represented as:

• A. Species $A (-)$; Species $B (0)$
• B. Species $A(+)$; Species $B(+)$
• C. Species $A (-)$; Species $B (-)$
• D. Species $A(+) $; Species $B(0)$

Answer 1

The Correct Option is A

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).
