Different marine organisms occupy characteristic habitats within the marine ecosystem based on their ecological niches: Ipomoea (a beach/dune vine) occupies the supralittoral zone above the high tide line; Avicennia (a mangrove tree genus) occupies mangrove habitats in intertidal muddy coastal areas; Xancus (a large marine gastropod, the chank shell) occupies subtidal sandy/muddy substrates; Zostera (a seagrass genus) occupies seagrass beds in shallow subtidal areas; Symbiodinium (zooxanthellae) lives symbiotically within coral tissue as a coral biont; and Dentalium (a scaphopod, tusk shell) is characteristically found in intertidal to shallow subtidal soft sediments.
Matching each organism to its characteristic marine habitat: Ipomoea sp (A), a dune/beach vine, is found in the supralittoral zone (S), above the normal high-tide...
