Symbiosis is a close and long-term biological interaction between two different biological species. The term symbiosis is derived from the Greek word symbios, meaning "living together". This interaction can be beneficial, neutral, or detrimental to one or both of the participating species. Symbiotic relationships are crucial to understanding ecology and biodiversity, as they often play significant roles in the survival and evolution of species.

There are several types of symbiotic relationships. Mutualism is a relationship where both species benefit. A classic example is the relationship between bees and flowers, where bees get nectar and pollen for food, and flowers are pollinated in return. Commensalism is a relationship where one species benefits, and the other is neither harmed nor helped. Barnacles attaching to whales is an example, as the barnacles gain a place to live and filter food, while the whale is unaffected. Parasitism is a relationship where one species, the parasite, benefits at the expense of the other species, the host. Fleas on a dog are a parasitic relationship, where the fleas feed on the dog's blood, causing harm to the dog.

Symbiotic relationships can occur on various scales, from microscopic interactions between bacteria and their hosts to large-scale interactions between plants and animals. These interactions can influence population dynamics, community structure, and the overall health of ecosystems. Studying symbiosis provides insights into the complex web of life and the interconnectedness of different organisms.
