Answer 2

Explanation:

The Earth’s atmosphere contains about 500 times more oxygen molecules than carbon dioxide molecules. The consequence is that only a very small amount of oxygen gets cycled in the atmospheric carbon cycle. The Earth’s atmospheric oxygen content is the product of photosynthetic lifeforms over billions of years.

Estimates for the Amazon rainforests’ effectiveness as a carbon dioxide sink suggest that a few decades ago it was absorbing about 2.2..2.4 billion tonnes of carbon dioxide per year and is now absorbing about 1..1.2 billion tonnes of carbon dioxide per year. A carbon dioxide molecule consists of a carbon atom and two oxygen atoms so the ratio of the mass of oxygen produced to carbon dioxide absorbed to oxygen produced is 811 . So that means that rainforests’ oxygen output is currently 720..870 million tonnes per year. That is less that one in a million of the oxygen molecules in the atmosphere comes from the rainforest in any year.
