Why Does My OBJ Model Look Like This?

Why does my obj 3d model have this? It is a bush and I it has these black panes around the bush itself and I do not know how to get rid of them? Do I edit the texture in a photo editing software?

Two screenshots below:

You are using the wrong shader. The bush texture (if set up properly) has an alpha channel that tells the shader what is visible and what is transparent.

Try some of the nature>leaves shaders, transparent shader, or transparent cutout shader.
