How much carbon (in g/m2) is released into the atmosphere as a result of the metabolic activity of herbivores? give your answer to the nearest whole number.\?

I think about 60 g/m^2 is released into the atmosphere as a result of the metabolic activity of herbivores. Metabolism is the sum of the chemical reactions that take place within a cell of a living organisms and that provide energy energy for vital processes and also for synthesizing new organic material. In herbivores, cellular respiration is the major process that releases carbon dioxide in the atmosphere.
