Question

Which of the following is NOT the function of dispersal behaviour in which organisms move away from their natal homes?

A.

Tracking resource availability

B.

Providing mating opportunities

C.

Preventing species extinction

D.

Avoiding pathogens

Correct option is C

Explanation-

Analyzing Each Option:
Option a -Tracking resource availability - Correct function of dispersal.
Dispersal helps organisms move to areas where food, water, or other resources are more plentiful.
Option b - Providing mating opportunities - Correct function.
By moving away from their birthplace, organisms reduce inbreeding and increase access to unrelated mates.
Option c - Preventing species extinction - Not a direct function of dispersal behaviour.
While dispersal may contribute to long-term species survival by increasing genetic diversity or colonizing new habitats, the primary aim of dispersal is not to prevent extinction. Extinction is a broader evolutionary and ecological outcome, not a direct function or mechanism driving dispersal.
Option d - Avoiding pathogens - Correct function.
Dispersal can help organisms avoid areas with high parasite/pathogen loads or reduce disease transmission among closely related individuals.

Final Answer:
Option c: Preventing species extinction
