New compounds with higher-energy bonds must be formed when the low-energy bonds in food molecules are broken.
B.
The energy in the new compounds that are formed must be equal to the energy in the bonds of the food molecules.
C.
New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.
D.
The new compounds that are formed must be more complex than the food molecules that were broken down.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
