During times of poverty or famine, people are often faced with a shortage of food. maxwell is studying how the energy in food is transferred from one trophic level to another in a food pyramid. he learns that by decreasing the number of trophic levels in a food pyramid, less energy is lost to the environment as heat. maxwell concludes that in times of food shortage humans should replace the in their diets with in order to decrease the number of trophic levels in their food pyramid.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!
