Sentences with phrase «new symbionts»

Whether coral die or not depends on how quickly new symbionts are acquired relative to how much energy the coral has stored, or coral's ability to feed on plankton as an alternative energy source.

Each polyp can be visualized as an upside down jellyfish (coral's close cousins) with their backs cemented to a surface and tentacles extended outward to capture passing food particles, live prey, or new symbionts.

Although bleaching can result in coral death due to starvation when new symbionts are not acquired quickly enough, surviving polyps with their altered symbiont community have the potential to re-direct the reef on a trajectory that is better suited to the new environment.
