Humans produce carbon dioxide while performing

a. aerobic respiration
b. citric acid fermentation
c. anaerobic respiration
d. lactic acid fermentation

The correct answer is option A.

Explanation:

The classical or typical cellular respiration that animals perform is called aerobic respiration. It begins in the cell cytoplasm, then continues in the mitochondria, where glucose is broken down and ATP is generated with carbon dioxide and water molecules.

     C₆H₁₂O₆ + 6O₂ →  energy(ATP) + 6CO₂ + 6H₂O

Thus, carbon dioxide is an end product of aerobic respiration performed by humans.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
