Oxygen-16 and Carbon-12 are stableisotopes of elements O and C respectively. Hence, they do not have half-lives. But Carbon-14 andUranium-238 are radioactive isotopes. Among them Carbon-14 has relatively short half-life as about 5730 years while Uranium-238 has a long half-life as about 4.5 billion years.
Answer is. uranium-238
Acidic basic alkaline neutral
Answer:
The point that does NOT accurately indicate a carbon transfer in the carbon cycle is that burning of wood and debris pulls carbon from the atmosphere to use as energy.
Explanation:
The carbon cycle involves the journey that carbon makes between living organisms and their surrounding environment, i.e. the entire biosphere, geosphere, hydrosphere and atmosphere, and is therefore considered a biogeochemical cycle.
In living organisms, inorganic carbon is taken up by plants to make organic molecules, which will be used by animals - which release CO₂ into the atmosphere - or dead organic matter provides carbon to the soil.
The combustion of wood and debris involves the oxidation of a combustible material -which requires oxygen from atmosphere- to then release CO₂ as a product. So it is incorrect to say that burning of wood and debris pulls carbon from the atmosphere to use as energy.
