Zoology - Organisms and Populations Question with Solution | TestHub
Which of the following statements regarding species interdependence are true?
I. An association of two species where one is benefitted and other remains unaffected is called mutualism.
II. An interspecific association where both partners derive benefit from each other is called commensalism.
III. A direct food relation between two species of animals in which one animal kills and feeds on another is referred to as predation.
IV. A relationship between two species of organisms where both the partners are benefitted from each other is called symbiosis.
Options:
Answer:
Solution:
Predation is a direct food relation between two species of animals, in which one animal (the predator) captures and feeds on another (the prey).
In symbiosis, two organisms live together in close physical association from which one or both derive benefit.
Mutualism: It confers benefits on both the interacting species. It is an obligate association of two organisms where two organisms often live together and cannot live separately.
Commensalism is the interaction in which one species benefits and other is neither harmed nor benefited. The species which is benefitted is termed commensal and the other species is called host.
