Explanation:
Neritic zone, also known as sublittoral zone, is a transition zone between the continental domain and the marine domain. It is the area that is under the influence of the tides and where light can penetrate to the bottom, promoting photosynthesis.
This zone is a complex, dynamic, changeable range and subject to various geological processes. The mechanical action of waves, currents and tides are important modeling factors of coastal zones, the results of which are erosion or deposition.
Answer:
Power is measured at three different levels pertinent to flapping flight.
