allelopathy

A biological phenomenon in him which one organism produces secondary metabolites that have either beneficial (positive) allelopathy or detrimental (negative) allelopathy on target organisms.

Examples of organisms displaying allelopathy
Plants, algae, bacteria, coral and fungi. These interactions influence species distribution and abundance within plant communities and ecosystems.
