what do you call an animal that eats minerals?

most all birds eat rocks too.

They need the rocks to help grind the food they eat as it passes through their gizzards.

Many birds are omnivorous as the rocks are NOT for nutritonal benefit but rather utilitarian, as a tool to grind thier feed.

You interestingly do no longer comprehend lots approximately how animals are killed. that is as an occasion in comparison to somebody stabs with a knife at a pig till it would not make a sound anymore and each thing around is a huge bloody mess. the oftentimes happening approach right now is a sort of vertical merry-circulate-around the place the pigs circulate down right into a sea of carbondioxide till they bypass out. Cabondioxide intoxication purely potential they nod off, whilst they drop out of that concern they're greater or much less lifeless and did no longer sense something. it particularly is something thoroughly diverse from you killing a cow interior the cafeteria. that will certainly be cruelty. And the beef could be detrimental besides reason it may be packed with stress hormones - which by potential of ways is why no actual meat lover buys the cheap junk from Wal-Mart. One steak much less a week, yet then a stable one.

lithovores but the concept is nonsense because rocks are not made of the right elements to act as food for a carbon based life form

hmmm.... I think elephants or maybe hippos eats rocks....to help with digestion
