What is the importance of struggle in Darwin's idea of natural selection?
Answer and explanation
Correct answer: With limited resources, organisms with better-adapted traits are more likely to survive and reproduce.
Darwin used the idea of struggle for existence to explain competition among organisms for limited food, space, shelter, and mates. Individuals in the same population vary, and some variations provide an advantage in a particular environment. Such organisms are more likely to survive and reproduce, passing those useful inherited traits to offspring. Therefore, option A is correct; the other choices incorrectly describe struggle as total death or as unrelated to biology.
