What soil factors influence type of vegetation in a region?

I am confused, so I provided two answers. I am uncertain of which one is correct, though.

My answer #1: Soil, temperature, and moisture influence the type of vegetation that thrives naturally in a region.

My answer #2: Such factors as depth, texture, and humus content of the soil determine the type of vegetation that can be supported in a region.
