All of these choices are correct

Explanation:

Carbon is recycled between the various systems of the earth through the carbon cycle. Carbon dioxide plays an essential role in the carbon cycle. Carbon dioxide is exchanged between the atmosphere and living organisms through the process of respiration. Also, the death and decomposition of living organisms release carbon dioxide in the atmosphere.

Plants make use of carbon dioxide in the atmosphere and water in the presence of sunlight to produce simple sugars. Thereby removing carbon dioxide from the atmosphere. However, at night, when plants respire, they break down the sugars for the production of energy. This process results in the production and release of carbon dioxide into the atmosphere.

Animals cannot manufacture their own food. However, they eat the food made by plants and break down the sugar molecules present in them using atmospheric oxygen and releasing carbon dioxide into the atmosphere in the process.

Also, the death and decay of plants releases the carbon stored in them in the form of carbon dioxide into the atmosphere.

Thus, from the options in the question, the correct answer is the last one: All of these choices are correct. This is because all the previous three options are all means by which the carbon dioxide absorbed by plants is returned to the atmosphere.
