Answer:
describes a process by which sediment, usually sand, lost through longshore drift or erosion is replaced from other sources. A wider beach can reduce storm damage to coastal structures by dissipating energy across the surf zone, protecting upland structures and infrastructure from storm surges, tsunamis and unusually high tides.[citation needed] Beach nourishment is typically part of a larger coastal defense scheme. Nourishment is typically a repetitive process since it does not remove the physical forces that cause erosion but simply mitigates their effects.

<em>Photosynthesis:</em><em> </em>is a cellular process during which light energy is absorbed by green pigments.
<em>Chloroplast:</em> a sub-cellular structure of plant cell.
<em>Chlorophyll:</em> a green pigment found within the chloroplast.
Phototropism is the growth of an organism<span> which responds to a light stimulus. It is most often observed in plants, but can also occur in other </span>organisms<span> such as </span>fungi<span>. The </span>cells<span> on the plant that are farthest from the light have a chemical called</span>auxin<span> that reacts when phototropism occurs.</span>
