Read this line from the text: In addition, they are greedy eaters with a fondness for small fish and crustaceans. What does greedy mean in this sentence? They take more than they need. They have little to fear from others. They cannot be controlled. They have a weight problem.

Explanation:

The lionfish is a species of fish which was introduced into the Atlantic ocean in the 1990's by accident. These fishes can adapt easily anywhere and has no natural prey to control its population.

Lionfish reproduce rapidly and its population has now become a threat to other fish populations in the ocean. They eat small fishes and other crustaceans in large quantity as their population cannot be controlled.

They are often called greedy as they consume a lot of food in the ocean which makes other fishes difficult to survive. Perhaps this can be attributed to the rapid increase of its population and the failure to control their rapid reproduction.

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
