- What are the distinctions between Non-extended SUSY and Extended SUSY?

(Is that just a non-extended SUSY has $\mathcal{N}=1$ while the extended SUSY has $\mathcal{N}>1$ ? Then there is no conceptual upgrade?)

2.

If we start from a non-extended SUSY, how to obtain an extended SUSY?

If we start from an extended SUSY , how to obtain a non-extended SUSY?

(via SUSY breaking? what else?)
