I believe the answer is B, the survival of the fittest due to competition for resources. Survival of the fittest is a term that originated from Darwinian evolutionary theory was a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success. Many organism overproduce to increase chances of survival for their organisms due to competition.
The correct answer is option B) "The survival of the fittest due to competition for resources"
Explanation:
Darwinian evolutionary theory explains that natural selection allows for the species improvement by the "survival of the fittest". Overproduction in a defined ecosystem would eventually lead to species improvement due to competition for resources. More individuals of animals and plants would need more resources to survive, the competition for resources would be a determinant factor for natural selection.
