Carbon - 14 can combine with oxygen in the atmosphere to create
carbon dioxide, which is then
absorbed by
plants and makes its way through the food chain.
While this controls the amount of
carbon dioxide they're
absorbing, it has the added outcome of limiting the amount of water released into the air from
plants.
Sometimes increased insulation due to a periodic shifting of the earth's orbit towards the sun will raise the temperature first and the
carbon dioxide will follow — with higher temperatures reducing the amount of
carbon dioxide which the ocean will have the capacity to hold — and the amount of
carbon dioxide which
plants are able to
absorb given droughts.
The Sun is important because it provides the Earth heat, it creates our daylight by emiting electromagnetic radiation, it allows
