Question

Association of cattle egret and grazing cattle represents :

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

Answer 1

The correct option is C Commensalism

Commensalism is a relationship between two organisms in which one benefits from the other without causing harm to it. The commensal organism obtains food, shelter, locomotion, or support.

The cattle egret and grazing cattle in a close association is a classic example of commensalism. It is a common sight in rural areas where one can see ticks hovering over the cattle. They feed on cattle's blood and hence are harmful to them as they can transmit several diseases.

Mutualism is defined as an interaction between individuals of different species that results in positive (beneficial) effects on per capita reproduction and/or survival of the interacting populations.

Ammensalism, association between organisms of two different species in which one is inhibited or destroyed and the other is unaffected.

Protocooperation is where two species interact with each other beneficially; they have no need to interact with each other - they interact purely for the gain that they receive from doing this.
