Question

A bird enters the mouth of crocodile and feeds on parasitic leeches. The bird gets food and crocodile get rid of blood sucking leeches. Both the partners can live independently. Such an association is

• A. Mutualism
• B. Amenalism
• C. Commensalism
• D. Protocooperation

Answer 1

The correct option is D Protocooperation

Protocooperation is the interaction between two living organisms of different species in which both are mutually benefited but they can live without each other. It is the non-obligatory, mutually beneficial relationship, that develops when two different organisms get associated e.g., Oxpecker (Buphagus) feeds on skin parasites of rhinoceros and crocodile. The bird (Pluvianis) rids crocodiles of leeches sticking inside their mouth.

Thus, the correct answer is option D.
