Solution
The inability of an organism to adapt to its habitat can lead to
A
dormancy
B
adaptation
C
extinction
D
survival
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
The inability of an organism to adapt to its changing habitat can indeed lead to extinction, as adaptation is crucial for survival and reproduction in a dynamic environment.
Organisms need to adapt to their environment to survive and reproduce successfully. Adaptations can be physical (like fur for warmth) or behavioral (like migrating for food).
