Answer:
The correct answer is - The birth of more offspring than can survive.
Explanation:
Overproduction takes place when species reproduce many more offspring than can really survive in nature. It is because of limited resources in a particular ecosystem.
Overproduction leads to competition for resources. It is one of the factors that can affect the process of natural selection. It can be responsible for the adaption and variation in species. Overproduction improves the genetic line by supporting the strongest characters by the survival of the fittest.
Thus, the correct answer is - The birth of more offspring than can survive.
