Demand and cost are inversely related, i.e., as the cost goes up, the demand goes down, and as cost goes down, demand goes up. So any two cost-demand curves are are inversely related constitute a perfect elastic supply curve.
When supply and demand are perfectly elastic/inelastic
The difference between individual supply curve and the market supply curve is tat individual supply curve is like a firm. To be able to get the market supply curve you have to have the individual supply curve.
Regard the "move-up"s of the whole industry's demand curve as a "dynamic process" at different times. When it happens to intersect with supply curve under perfect competition, we get the equilibrium price and quantity. At this time, firms seem like find their best "time" in the "dynamic process". So during this "time", the price for firms is perfect elastic because neither consumers would buy the product at a higher price nor firms would sell the product at a lower price. To sum up, the difference is -- the firm has a horizontal demand curve while the industry has a down-slope one under perfect competition.
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.
Several factors can affect an abnormal supply curve, including production costs, technological advancements, and government regulations. Changes in input prices can shift the supply curve, as can external shocks like natural disasters or geopolitical events. Additionally, market expectations and the number of suppliers in the market can influence supply dynamics. Lastly, factors like taxes and subsidies can also lead to shifts in the supply curve.

A diagram of a perfectly competitive market typically shows a horizontal demand curve representing perfect competition, a horizontal supply curve at the market price, and a point where supply equals demand to show equilibrium. It also includes the producer and consumer surplus to illustrate market efficiency.
a change in supply is the shift in supply curve due to change in price of other commodities and other factors like taste,weather,income e.t.c while a change in quantity supply is the change in price of the commodity itself that affect the quantity supply,here the supply curve remain constant but there will be a movement along the supply curve.
A change in supply is represented on a graph by a shift of the supply curve to the left or right. If supply increases, the curve shifts to the right, indicating that producers are willing to supply more at each price level. Conversely, a decrease in supply shifts the curve to the left, showing that less is available at each price. This shift affects the equilibrium price and quantity in the market.
The short-run aggregate supply curve is horizontal if the economy is operating below full capacity, meaning there are unused resources like labor and capital. This indicates that firms can increase production without raising prices, resulting in a flat supply curve.
The supply curve of a pure monopolist is not well-defined like that of a competitive firm because a monopolist sets prices based on demand rather than producing a specific quantity at a given price. Instead of a typical upward-sloping supply curve, a monopolist determines the quantity to produce by equating marginal cost with marginal revenue, and then uses the demand curve to set the price. Consequently, the monopolist's pricing and output decisions are influenced by the market demand, leading to a downward-sloping demand curve rather than a distinct supply curve.
The individual supply of labor curve represents the relationship between the wage rate and the quantity of labor an individual is willing to supply, reflecting personal preferences and constraints. In contrast, the market supply of labor curve aggregates the individual supply curves of all workers in the market, illustrating the total quantity of labor supplied at various wage rates. While the individual curve is based on personal factors like skill level and circumstances, the market curve reflects broader trends and influences, including overall demand for labor and economic conditions.
