Zombies are one of the first mobs, or mobile entities, in Minecraft. The zombie attacks you dealing damage depending on your difficulty setting and what armor you are wearing. Zombies also attack villagers and upon killing them, turn them into zombie villagers.(Zombie villagers can be healed when affected by weakness and fed a normal golden apple.) Zombies spawn in villages, dark areas, and when it is night. If an area is well lit a zombie cannot spawn unless its a siege in a village. The zombies will set on fire when exposed to daylight. On rare occasions zombies can pick up drop items and wield them as weapons or if it is armor or a head, as clothing. (Zombies do not set on fire by the sun if wearing head gear.) On normal difficulty or higher zombies can also break down wooden doors after repeated hits.
you cant
they don't drop anything but if you have bones and feed it to them you get them to fight for you Hope This Helped! :)
To get Iron ingot in Minecraft you can either kill zombies (but that may take forever to find a zombie that will drop it) or depending on the server you can get to level 10 in an arena. Also someone might be selling it. :) To purchase it is the easiest way to get it in my opinion.

As of 1.4.2, some monsters drop their heads as trophies when killed. A head from a Skeleton or a Wither Skeleton, is a skull.
bones
simply kill wither skeltons that can be found in nether fortresses. there is a 0.8 percent chance that they will drop a wither head, however with a looting enchant this will be boosted up to a 2.5 percent chance.
Because they"re birds!
