Question

Which of the following statement(s) is incorrect?
I. In amensalism, one species is benefitted while the other is unaffected.
II. Predator is an organism that catches and kills the other organism for food.
III. Mutualism is a type of population interaction in which both the species are harmed.

• A. I and II
• B. Only II
• C. Only III
• D. I and III

Answer 1

The correct option is D I and III

Interaction of populations of two different species lead to interspecific interactions. They could be beneficial, detrimental or neutral (neither harm nor benefit).

Predation, commensalism, amensalism, parasitism are the different types of population interactions.

Amensalism is association between organisms of two different species, in which one species is harmed and the other is unaffected (neither benefited or harmed).
Therefore, the statement I is incorrect.

Predation is a type of interaction, in which an organism called the predator eats another organism called the prey. Hence, out of the two species, one is benefited and the other gets harmed.
Therefore, the statement II is correct.

Mutualism is a type of population interaction where both the interacting species live in close association and are benefited mutually.
Therefore, statement III is incorrect.
