Detailed explanation-1: -The process of photosynthesis2 explains why forests function as CO2 sinks, removing CO2 from the atmosphere. Atmospheric CO2 is fixed in the plant’s chlorophyll parts and the carbon is integrated to complex organic molecules which are then used by the whole plant.

Detailed explanation-2: -Forests help to slow the rate of climate change by removing carbon dioxide from the atmosphere and storing it. This is a direct effect, as the primary driver of climate change is the over-abundance of carbon dioxide in the atmosphere.

Detailed explanation-3: -Forests are typically carbon sinks, places that absorb more carbon than they release. They continually take carbon out of the atmosphere through the process of photosynthesis. The ocean is another example of a carbon sink, absorbing a large amount of carbon dioxide from the atmosphere.

Detailed explanation-4: -A forest is considered to be a carbon sink if it absorbs more carbon from the atmosphere than it releases. Carbon is absorbed from the atmosphere through photosynthesis. It then becomes deposited in forest biomass (that is, trunks, branches, roots and leaves), in dead organic matter (litter and dead wood) and in soils.

Detailed explanation-5: -A carbon sink absorbs carbon dioxide from the atmosphere. The ocean, soil and forests are the world’s largest carbon sinks. A carbon source releases carbon dioxide into the atmosphere. Examples of carbon sources include the burning of fossil fuels like gas, coal and oil, deforestation and volcanic eruptions.
