. Information in the passage indicates that the author would most probably regard which of following statements as INCORRECT? (A) Coastal mangrove forests are usually zonal. (B) Hurricanes interrupt the process of accretion and succession that extends existing shorelines. (C) Species of plants that thrive in a saline habitat require salt to flourish. (D) Plants with the highest metabolic efficiency in a given habitat tend to exclude other plants from that habitat. (C) (E) Shoreline in areas with weak currents and trides are more likely to be extended through the porocess of accumulation of sediment than are shorleines with strong currents and tides. Recently the universal application of Davis’s succession paradigm has been challenged. It appears that in areas where weak currents and weak tidal energies allow the accumulation of sediments, mangroves will follow land formation and accelerate the rate of soil accretion; succession will proceed according to Davis’s scheme. But on stable coastlines, the distribution of mangrove species results in other patterns of zonation; “land building” does not occur.
