How did the Germans starve people in Leningrad?

During World War II, the Germans implemented a brutal siege of Leningrad (now St. Petersburg) from September 1941 to January 1944, effectively cutting off the city from essential supplies. They blocked all land and water routes, preventing food and resources from reaching the civilian population. As a result, the residents faced extreme starvation, with rations dwindling to as little as 125 grams of bread per day, leading to widespread famine and suffering. The siege claimed the lives of an estimated one million civilians due to starvation, cold, and bombardment.
