was What is the first stage of production? Increasing marginal returns Decreasing marginal returns Negative marginal returns

The first stage of production is characterized by increasing marginal returns. This is when the addition of more units of a variable input (such as labor) to fixed inputs (such as capital) results in an increase in the marginal product of the variable input. In other words, each additional unit of input contributes more to the total output than the previous unit. This stage typically occurs when the level of input is relatively low.
