Question

The interaction between “Cuckoo and Crow” is an example for
A) Competition
B) Predation
C) Brood parasitism
D) Mutualism

Answer 1

Hint: In the case of Cuckoo and crow, one is dependent on the other and vice versa. When cuckoo laid eggs it kept that in the crows nest at their younger phase.

Complete Answer:
A) Competition is the relationship between two organisms that takes place due to unavailability of food, space or survival. As a result, one competitor is always harmed at the end and becomes extinct. It may be of two types: intra competition and inter competition. It is suppressed only by the environmental disturbance.

B) Predation is a biological interaction where one organism, the predator, kills and eats another organism is its prey. Predation is referred to as a flow of energy that occurs between two organisms, predator and prey. As a result, the prey loses energy, and the predator gains energy.

C) Brood parasitism is when eggs are laid on the nest of another bird. Parasitic parents are relieved from building nests for the young and it enables them to give more time on other activities like forage and production of further offspring etc..

D) Mutualism is the interaction between two organisms where both of them will be benefitted. Mutualism is a common type of ecological interaction.Mutualism is often conflated with two other types of ecological phenomena: cooperation and symbiosis. It is found between rhinoceros and oxpecker.

Hence Option C: Brood parasitism is the correct answer.

Note: Mutualism, parasitism, predation and all are the examples of biological interaction. Beside these there are other one named ammensalism which is also a biological interaction between species.
