As a result, wetlands are very good carbon sinks (meaning they store a lot of carbon). In summary, coastal wetlands are particularly good at storing carbon because the plants annually sequester (capture) a lot of carbon and then these ecosystems store carbon for long periods of time in their soils.
There are three naturally occurring isotopes of carbon: 12, 13, and 14. 12 C and 13 C are stable, occurring in a natural proportion of approximately 99:1. 14 C is produced by thermal neutrons from cosmic radiation in the upper atmosphere, and is transported down to earth to be absorbed by living biological material.arbon-15 redirects here. For the firearm, see Carbon 15. Carbon (C) has 15 known isotopes, from 8 C to 22 C, 2 of which (12C and 13C) are stable. The longest-lived radioisotope is 14C, with a half-life of 5,700 years.
