Differentiate between cow farming and goat farming​

Explanation:

Goats can be large, but usually not THAT big. A good mini cow will still weigh in at 400-500 pounds. ... Cow's teats are generally bigger, too, but not always - it depends on the breed. A good Nubian doe can put a Jersey cow to shame in the size department.

the sun creates it's own light, also gives light and life to bunch of stuff like plants,animals,humans etc.photosyntesis is the process of making food which needs sun,water,nutrients etc.
