2. paragraph
The ( ) slowing of ( )wave action and ( )currents means
that ( )seagrass beds tend to accumulate ( )sediment.
However,
this is not universal
and depends
on the ( )currents
under which the ( ) bed exists.
Seagrass beds
under the influence of ( )strong currents
tend to have many of the ( )lighter particles,
including ( )seagrass debris,
moved out,
whereas ( ) beds
in weak ( ) current areas
accumulate ( ) lighter detrital material.
It is interesting
that ( ) temperate seagrass beds accumulate ( ) sediments
from ( ) sources outside ( ) the beds,
whereas ( ) tropical seagrass beds
derive most of their ( ) sediments from within.
