Question

The interspecific interaction in which one partner is benefitted and the other is unaffected (neutral), is called

(a) amensalism
(b) mutualism
(c) competition
(d) commensalism
​​

Answer 1

The answer is (d) commensalism.

Step-by-step explanation:

Commensalism is an interspecific interaction in which one partner benefits and the other is unaffected (neutral).

Mutualism is an interspecific interaction in which both partners benefit.

Competition is an interspecific interaction in which both partners are affected as they compete for resources or space.

Amensalism is an interspecific interaction in which one partner is harmed while the other remains unaffected.

• So, option (d) is correct because it describes an interaction in which one partner benefits while the other is unaffected.

• The other options are incorrect because they describe interactions in which both partners are affected in some way.

Answer 2

(d). commensalism

Step-by-step explanation:

The interspecific interaction in which one partner is benefitted and the other is unaffected (neutral), is called commensalism.

So the answer is (d). commensalism

• Amensalism is an interaction in which one organism is harmed and the other is unaffected.
• Mutualism is an interaction in which both organisms benefit.
• Competition is an interaction in which both organisms are harmed.

In commensalism, one organism benefits from the interaction while the other organism is unaffected.

barnacles that attach themselves to the hull of a ship benefit from the ship's movement and currents, while the ship is unaffected.
