The goal of cellular respiration is to produce carbon dioxide by using oxygen. The final product can be used later on for photosynthesis.
The second process requires carbon being put back into the process it used to be in, unlike when it was in any dead organism. Waste products are broken down through this never ending product. The main goal of decomposition through the carbon cycle is to free carbon through another process called cellular respiration.
Because of the limit of the growth( ex, temperature, precipitation, sunlight soil)
The R-COOH. Unbranched hydrocarbon chain with carboxyl at one end. science textbook :)
B) Primary producers. Autotrophs are organisms that produce their own food through photosynthesis, which are primary producers.
