Symbiosis

Symbiosis is a close and long-term relationship between two or more different species of organisms. It can be either mutually beneficial or harmful. Mutualistic symbiosis is when both organisms benefit from the association, for example, nitrogen-fixing bacteria found in the root nodules of legumes. In contrast, parasitic symbiosis is when one organism benefits at the expense of the other, such as the relationship between ticks and deer. Understanding symbiosis is important in many aspects, such as medicine, agriculture, and restoring ecosystems. Additionally, the knowledge of symbiosis helps us to better understand the evolution of species and their inter-dependency on each other.
