In Darwin's theory of natural selection, what process is intensified by limited resources?
Answer and explanation
Correct answer: Struggle among organisms and survival of individuals with advantageous traits
The governing concept is the struggle for existence. Organisms produce more offspring than the environment can support, while food, space, shelter, and mates are limited. Competition therefore increases, and individuals with heritable traits that improve survival or reproduction are more likely to leave offspring. Across generations, these traits may become more common through natural selection. Hence A is correct; B, C, and D have no biological basis.
