Answer: Gut microbiome degrade the ingested milk sugars through a biochemical pathway, producing ATP required for the energy needs of infant.
Explanation:
The human breast milk fed on by infants contains a high concentration of indigestible oligosaccharides which include lacto-N-tetraose and lacto-N-fucopentaose.
These milk sugars are utilized by microbes in the gut of infants, yielding lactate as the final product of metabolism and releasing several molecules of ATP as useful energy for use by the infant.
Thus, the presence of these gut microbes at birth, and the feeding of infant with breast milk is vital to fulfilling their energy needs
When the bird is decomposed, more energy is transfered since its's bigger than a fly, a spider and the amount of fruit a fly can eat.
