What were there different methods for executing the Jews?

The way Hitler would execute Jewish people involved him shooting, gas chambers, starvation. They were some of the mains reasons Jewish people died from Hitler. He would not feed the enough food which consisted of only bread and water usually and even then it was very little meaning a lot of Jews died from starvation.

Most of the ways Jewish people died was because of the gas chambers which were made to look like showers its when after Jewish people step in the room is made airtight so it gets full up with gas that would kill them.

Some Jewish prisoners died to disease which they would have caught because of rats the germs from the bathroom meaning loads of Jewish people died due to it such as Anne Frank who hid until her capture. She was sent an immediate death along with her sister to the gas chambers. But were spared and sent to a different concentration camp where they both died to a disease.
