The process of cellular respiration begins with molecules of glucose and ends with production of energy.

Explanation:

Cellular respiration is the process that takes place inside living cells and the initial process is glycolysis. The process of glycolysis breaks down the glucose molecules which contain 6 carbon atoms each into two three-carbon pyruvate molecules.  

The output of cellular respiration is energy. The energy produced in cellular respiration is in the form of ATP. Respiration is an exothermic process and two ATPs are produced as a result of cellular respiration.  

it is a limiting nutrient limited by a single nutrient in the ecosystem, & the single goes very slow.
