Question

Relationship between two organisms in which one obtains some benefits at the cost of other is

• A. Parasitism
• B. Predation
• C. Symbiosis
• D. Scavenging
• E. Commensalism

Answer 1

The correct option is A Parasitism

Parasitism is a type of population interaction in which one organism lives on or inside another organism. The former is a parasite and the latter is a host. Parasite thrives on the food of the host and takes away its nutrition. Thus the parasite benefits. But the host is harmed.

So, option A is the correct answer.
