We have to understand that cellular respiration is something which happens for all organisms and all ecosystems .
In some ecosystems, such as tropical rainforests, decomposition is accomplished quickly, and carbon dioxide is returned to the atmosphere at a relatively fast rate.
In other ecosystems, such as northern forests and tundra, decomposition proceeds more slowly.
In some places, such as bogs and the deep ocean, the organic matter of plants and animals may accumulate in deep sediments, where decomposers cannot function well because of the lack of oxygen. over millions of years, the carbon-rich materials are converted into carbon-rich fossil fuels, such as petroleum, natural gas, and coal. Also in marine environments, carbon-containing matter (such as calcium carbonate) is incorporated into the shells and other hard parts of aquatic organisms. When these organisms die, the carbon-rich hard parts sink to the ocean bed. There they become buried in sediment, and eventually densify into rocks such as limestone and dolomite.
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation. These stages includes the utilisation of carbon dioxide by plants and lower animals
