Why don't these Minecraft mods work together?

[Petzbreeder]

I have three mods installed on Minecraft 1.7.10 called AntMan, iChunUtil and Morphing mod.

This is the error message I get when trying to load Minecraft. I don't know what it means.

Why don't the mods work together?

Download the mods here to try them yourself. The Forge installer is included.

As it turns out, I was missing Render Player API.
