Final answer:

The correct statement about Maximum Sustainable Yield is that it aims to maximize resource extraction without depleting the population, considering the species' reproductive capacity and growth rates. Data on phytoplankton levels and mussel biology would be best for determining the sustainable yield of mussels. The economic tradeoff between economic output and environmental protection is depicted by the production possibility frontier, preferring choices on the frontier over inefficient points.

Step-by-step explanation:

The correct statement about Maximum Sustainable Yield (MSY) is b) MSY aims to maximize resource extraction without depleting the population. The concept of MSY is used in the context of fisheries, wildlife management, and forestry to describe the maximum amount of a resource that can be harvested without compromising the future availability of that resource. To achieve MSY, managers of natural resources must consider factors like the reproductive capacity and growth rates of species while also accounting for natural mortality and environmental variations.

To justify or refute the suggestion that phytoplankton availability may be the limiting factor for mussels, data on the following would be crucial:

  • Phytoplankton levels in the estuary waters
  • Feeding rates and dietary requirements of mussels
  • Reproductive rates and population dynamics of mussels
  • Ecosystem health and other potential limiting factors

In the context of the production possibility frontier (PPF), there is a tradeoff between economic output and environmental protection. Efficient choices lie on the PPF, while inefficient choices like point M, which provide neither the maximum economic output nor the maximum environmental protection, are to be avoided. In contrast, market-oriented environmental policies strive to either reduce costs while maintaining the same level of environmental protection or improve environmental protection without increasing costs.
