Predation

Q.

If a trait A exists in 10% of a population of an asexually reproducing species and a trait B exists in 60% of the same population, which trait is likely to have arisen earlier?

Q.

Which of the following statements regarding species interdependence are true?
I. An association of two species where one is benefitted and the other remains unaffected is called mutualism.
II. An interspecific association where both partners derive benefit from each other is called as commensalism.
III. A direct food relation between two species of animals in which one kills and feeds on another is known as predation.
IV. Neutralism is where neither population affects the other.

1. I and II only
2. III and IV only
3. I and III only
4. II and III only
