Which food source contains the most energy?
If an bird was traveling south for the winter, which food source would contain the most energy for a bird preparing to migrate?
A:High sugar berries
B:High protein insects
C:High Fat seeds
A fat molecule yields more than twice the energy of sugar and protein in cellular respiration. Migratory birds would be wisest to chose the high fat seeds. However, for immediate energy, the high sugar berries would be a better option.
