* Cows eat grass: This is correct. They are herbivores and their diet primarily consists of grass, hay, and other plants.
* Grass is turned into milk: This is where it gets a little more complex. The grass isn't directly transformed into milk. Instead:
* Digestion: The cow digests the grass in its stomach, breaking it down into nutrients.
* Nutrients: These nutrients are then absorbed into the cow's bloodstream.
* Milk production: The cow's body uses these nutrients to produce milk in its mammary glands.
So, it's not a direct transformation, but the grass provides the essential building blocks for the cow to produce milk.
