english: Sometimes what's going on is that the microbes are helping them digest food more efficiently from the same diet, so they're taking more energy from their food, but other times, the microbes are actually affecting their behavior.
non_english: Ponekad se dešava da im mikrobi pomažu da efikasnije vare hranu iz istog načina ishrane, tako da dobijaju više energije iz hrane ali u drugim slučajevima, mikrobi zapravo utiču na njihovo ponašanje.
