There is a natural number which when added to a natural number, gives the number itself.

False.

∴ 0 is the identity for addition of numbers i.e.
If n is a natural number, then n + 0 = n.
But 0 is not a natural number.
∴ It is false.

1 is the identity for multiplication of whole numbers.

There is a whole number which when added to a whole number, gives the number itself.

If a whole number is divided by another whole number, which is greater than the first one, the quotient is not equal to zero.

Any non-zero whole number divided by itself gives the quotient 1.
