Gov responsibilities

In a communistic country, the government is responsible for EVERYTHING. They provide for all that is needed to run a country and to provide for the people, the only downer is that you have almost no say in what you do and what religion you are a part of.
A mixed economy's government is responsible for establishing boundaries of states, supplying the people with defenses and protection, healthcare, transportation/ roads, and so forth.

Mixed vs communist economy & natural resources

A mixed economy is a collaboration of socialist and market economies. For the most part the people decide what is produced and how to produce it. But, the government also oversees certain aspects of these products and only allows certain companies to make that particular product, and oversee who can and can't buy it.
A communist, or command economy as they are often called, is completely governmentally owned and operated. Most if not all businesses are owned by the government and only extremely small businesses are privately owned. The people have no say in what is produced.
