Marginal cost curve is u-shaped curve, this is due to law of variable proportion(return to factors), firstly, there is an increasing return (i.e, decreasing cost) then there is a stage of constant returns (i.e, constant cost) then lastly comes the stage of decreasing returns (i.e increasing cost), that`s why marginal cost curve first slopes downward and then slope upward and become u-shaped.

Marginal Benefit curve is usually downward sloping, while Marginal Cost is usually upward sloping.
This question reflects a fundamental misunderstanding of supply and demand. Marginal revenue and average revenue are related to a firm's cost function, and are thus connected to SUPPLY. They have nothing to do with a demand curve in classical economics, which is the marginal benefit to the CONSUMER of being in the market.
When average total cost curve is falling it is necessarily above the marginal cost curve. If the average total cost curve is rising, it is necessarily below the marginal cost curve.
Flase, The suuply curve of a "perfect competition" is its marginal cost curve
In the long run, the perfect competition graph shows a horizontal demand curve and a downward-sloping supply curve intersecting at the equilibrium point, where price equals marginal cost. This results in maximum efficiency and zero economic profit for firms.
