Question

Write a short note on mutualism.

Answer 1

1. Mutualism is a type of symbiotic relationship where both species involved benefit from the association.
2. This interaction helps both organisms survive, grow, or reproduce better. For example, lichens are a mutualistic association between fungi and algae.
3. Another example is the nitrogen-fixing bacterium Rhizobium, which benefits the plant by fixing atmospheric nitrogen, while the plant provides nutrients to the bacteria.
4. Mutualism is essential for ecological balance and enhances the chances of survival for species.
