Noach was told to take a pair (male & female) of all non-clean animals, and 7 pairs of clean animals into the ark. However, Breishit 6:21 says:
And take thou unto thee of all food that is eaten, and gather it to thee; and it shall be for food for thee, and for them
Considering that many animals are carnivores, does that mean that Noach took extra animals as food for the other animals? If so, should we assume that all that food was eaten or was there a possible food shortage or leftover live animals? Was Noach an expert in animal food consumption, assuming that each animal ate the same quantity (for that animal), daily?
