Gause's principle of competitive exclusion states that
The process where a population inhibits the growth of other population without affecting itself is known as
Amensalism is an interaction between two living individuals or populations of different species in which one organism or population does not allow, other organism or population to grow or live near it. Inhibition is achieved through the secretion of chemicals called allochemics. E.g., the roots and hulls of black walnut (Juglans nigra), produce a chemical called juglone. It is toxic to apple, tomato and alfalfa.
