Question

Write a short note on antibiosis.

Answer 1

1. Antibiosis is an interaction between two species where one species produces substances that are harmful or inhibitory to the other species.
2. This adverse effect on one organism is caused by chemical compounds or antibiotics produced by the other organism.
3. Antibiosis is a natural biological phenomenon often observed between microorganisms, such as fungi producing antibiotics that suppress bacterial growth.
4. This interaction helps control the population and maintain ecological balance. It differs from competition as antibiosis involves the production of biochemical agents hindering another organism’s growth or survival.
