Question

Quizplus · Accepted Answer

Total product begins to fall when the marginal product becomes zero. This happens because the marginal product represents the additional output that is generated by adding one more unit of input. When the marginal product becomes zero, it means that adding more inputs does not increase the output, and may even cause a decrease in the total product.
