I think that the correct answer is reactants of photosynthesis.
.5 of a micrometer in width
2 micrometers in length
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.
Answer:
Lots of bacteria are present as the microflora of a baby's gut which helps it to extract the nutrition from mother's milk and also helps the baby to maintain a low number of pathogenic bacteria in its gut.
Some bacteria present in the baby gut release enzymes like glycoside hydrolase which helps baby to digest carbohydrate present in the mother's milk.
Bacteria like Bifidobacterium, Streptococcus, Staphylococcus are already present in breast milk which helps in making gut microflora of baby and this gut microflora helps in extracting nutrients from mother's milk.
