The relationship between G-d and man is very simple. We humans are needy. We are dependent on G-d. The reason why we are created this way that is G-d wanted to us to acknowledge HIM.
This is why G-d made us dependent on food because HE wants to see us and realize we are depend on G-d for our very lives.
And this is what makes us human beings different from a plant and animal we are needy. We are created with needs.
