Answer 1

Cows eat plants and break them down. They also convert some of these nutrients into others using science and stomach acid and stuff. Then they poop out nutrient rich and easily absorbed poop and the plants eat it. Doesn’t make much sense to me but I’m not a scientist. I know the conversion that happens inside has to do something. Otherwise I would think that if a plant is high in a nutrient, the cow eats it and either absorbs the nutrient, then the poop or worthless or doesn’t absorb it and then what was the point of the plant absorbing that nutrient at all if it just produces it. There’s no loss. Idk
