The model, which was based largely brief supplynitrogen to get a plant on poor soil, as an illustration, or on empirical data, is reasonably unperturbed by modifications in iron for phytoplankton within the open ocean. For the longlived hydrocarbon seep rate, or inside the growth and recruitment prices for tubeworm Lamellibrachia luymesi, what it needs most and has the colony. The authors note that least is sulfide.

Their model predicts sulfide the way plants use sunlight, this to happen right after about 50 years, extracting power and releasing in line with observed reductions in the waste products, within this case tubeworm recruitment in colonies sulfate. of this age. They propose that Using a lifespan of as much as 250 carbonate precipitation might be years, L. luymesi is among the inhibited if roots may also release longestlived of all animals, but hydrogen ions, a possibility open how it obtains sufficient sulfide to to additional testing. Their model also keep going for this extended has been explains many biogeochemical a mystery. In this problem, Erik Cordes anomalies observed close to and colleagues propose a model tubeworm colonies, including in which, by releasing its waste elevated levels of extremely degraded sulfate not up in to the ocean hydrocarbons and greater than but down into the sediments, L. predicted rates of sulfur cycling. luymesi stimulates the development of To date, the proposed return sulfideproducing microbes, and of sulfate for the sediments ensures its personal longterm survival.
