Answer: According to the given diagram.
Atmosphere- source
Factories, power stations and vehicle emissions- source
Fossil fuels (coal, oil, natural gas)- source
Plants- sinks
Animals- source
Step-by-step explanation:
According to the given diagram.
Atmosphere- source
The atmosphere is the mass of different gases. The carbon dioxide is the gas which is also present in the atmosphere. The atmosphere is the source of carbon dioxide.
Factories, power stations and vehicle emissions- source
The factories, power stations and vehicle emissions emit the carbon dioxide gas into the atmosphere as they use the fossil fuel as a source of thermal energy.
Fossil fuels (coal, oil, natural gas)- source
When the fossil fuel burns they emit immense amounts of gases such as carbon dioxide and carbon monoxides in the atmosphere. Hence, they are the source of carbon.
Plants- sinks
Plants require carbon dioxide as reactant for the purpose of photosynthesis. Therefore, they absorb the carbon dioxide from the atmosphere. Hence, they called as carbon sinks.
Animals- source
The animals release carbon dioxide in the atmosphere which is a byproduct of the process of respiration.
