I would say false
Have a good day!
The correct option is this: The forelimbs (or possibly hind limbs) will be used for the new purpose of flight. This new function will arise through many gradual steps, and there will be aspects of the wing that reflect its history and are not perfectly suited for flight.
Adaptation refers to the physical or behavioral traits that an organism develop in order to enhance its suitability to its environment. Evolution on the other hand is always brought about by natural selection; organisms that are well adapted to their environments are naturally selected to survive, reproduce and pass their beneficial traits to their offspring. This is a gradual process that occurs over a long period of time.
For wings to develop in a four limbed organism, the organism has to start using the hind or the fore limbs for flight (New adaptive behavior). The genes that support this new behavior will be passed to its offspring and subsequent generations over a long period of time, until the wings are perfectly suited for flight.
An example of marine parasitism is a fish tapeworm that invade a fish's stomach and intestines.

Some possibilities of why a population decreasing are:
-invasive species
-deforestation
-pollution
-habitat loss
-change in food chain/web
-oil spills
