Answer: C. proteins

Explanation: In humans, ingested proteins are degraded into their constituents amino acids in the stomach. When dietary protein enters into the stomach, it stimulates the gastric mucosa to secrete the hormone gastrin.

Gastrin in turn stimulates the chief cells of the gastric glands to secrete pepsinogen. Pepsinogen is an inactive precursor or zymogen that is then converted to active pepsin through enzymatic cleavage.

Pepsin hydrolyzes the peptide bonds of the ingested proteins proteins at the amino terminal side of aromatic amino acid residues such as phenylalanine, tryptophan and tyrosine, cleaving long polypeptide chains into a mixture of smaller peptides.

konstantin123 [22]
When energy passes from one trophic level to the next, I would guess that the two factors which decrease the total amount of energy from being passed up are: 
1. An organism does not assimilate all the energy of food consumed. Within a consumer, digestion and assimilation of energy is not 100% efficient: some of the energy is lost.
2. A large proportion of energy assimilated by a producer and consumer is lost through respiration, i.e., day-to-day maintenance of metabolic processes.
