Question

The process where a population inhibits the growth of other population without affecting itself is known as:

• A. Amensalism
• B. Parasitism
• C. Commensalism
• D. Mutualism

Answer 1

The correct option is A Amensalism

Amensalism is an interaction between two living individuals or populations of different species in which one organism or population does not allow, other organism or population to grow or live near it.

Inhibition is achieved through the secretion of chemicals called allochemics. E.g., the roots and hulls of black walnut (Juglans nigra), produce a chemical called juglone. It is toxic to apple, tomato and alfalfa.

Parasitism is defined as the relationship between different species in which one organism lives on or in the other organism and benefits from it by causing some harm. The type of interaction in which one species benefits and the other is neither harmed nor benefited is called commensalism. Mutualism is the interaction between two living organisms where both the organisms are equally benefitted and no one is harmed.

So, the correct answer is "option A".
