Detailed explanation-1: -The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun’s energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

Detailed explanation-2: -Redwoods store 2, 600 metric tons of carbon per hectare (2.4 acres), more than double the absorption rate of the Pacific Northwest’s conifer trees or Australia’s eucalyptus forests, the study found. The main reason redwoods surpass all others in CO2 storage is their longevity, the scientists said.

Detailed explanation-3: -Carbon capture champions Earlier research by scientists at Humboldt University and the University of Washington found that Redwood forests store almost 2, 600 tonnes of carbon per hectare, their bark alone containing more carbon than any other neighbouring species.

Detailed explanation-4: -According to the Arbor Day Foundation, in one year a mature tree will absorb more than 48 pounds of carbon dioxide from the atmosphere and release oxygen in exchange.
