In the citric acid cycle, the acetyl group of each molecule of acetyl-CoA is converted into two molecule of carbon dioxide and water. It is the pathway that connects carbohydrates ,fat and protein metabolism.
The cycle which carried out by eight enzymes that completely oxidase acetate by which two carbon molecules in the form of acetyl -CoA into two carbon dioxide and water molecules.6- carbon glucose molecule is split into two 3- carbon molecules called pyruvate , which needs in order to create acetyl CoA.
Citric acid cycle is also known as krebs cycle or TCA cycle it is the series of chemical reactions to release to releases stored energy through the oxidation of acetyl-CoA from carbohydrate, fats and protein.

They are mostly habittated to watter because they requres oxygen more from water or there organ setup to do it works properly under water.
        
             
        
        
        
Answer: 
There are many things that can be considered as a limiting factor   such as water supply, competition, habitat space et cetera.
These factors affects the carrying capacity of the given environment. The human beings, animals uses food, space and water as their basic need.
These can affect the population of the organism if any of given components are presented in a limited amount.
The example of limiting factor that is human being to control the carrying capacity is food, space and water.
 
        
             
        
        
        
It would decrease as their prime food source would be taken away. This would result in a decline in population as the birds wouldn’t have sufficient food.
Hope that helps. :)
