These adaptations are so successful that some mangroves are able to grow in soils that reach salinities up to 75 parts per thousand (ppt), about two times the salinity of ocean water. The trophodynamics difference of OPEs may be attributed to food chain length, feeding habits and habitat of organisms, and biotransformation of OPEs in organisms. Once the leaves and older trees die they fall to the seafloor and take the stored carbon with them to be buried in the soil.
