Answer to Question 1

ANS: A
There needs to be a balance of production, distribution, and consumption of goods. Marine ecosystems
have various people and governments dictating which goods to produce, how to produce them, and
how to distribute these goods to the consumers. Information can be found in the section Marine
Resources Are Subject to the Economic Laws of Supply and Demand.



Answer to Question 2

ANS:Answer
should include:
 Organisms that reside in the estuary must be able to adapt to their rich yet variable
environment.
 Some estuarine plants are able to reduce the amount of erosion near them by changing
the flow of currents. They are able to trap silt particles and sediment at the base of their
roots. This makes their position more stable.
 The plants of the estuary have variations in the root systems. Small plants are prone to
having tiny projections that anchor them to the substrate while larger plants exhibit
elaborate root systems.
 Most residents of the estuary burrow into the muddy substrate. This behavior gives them
access to a high level of nutrients while providing shelter.
 Pelagic species use the estuary as marine nurseries. Many fish lay their eggs in the
estuary because they gain protection from the oceanic predators. Also, the larvae are
able to take advantage of the high nutrients during vital growth stages of their life.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
