Symbiotic Relationships

Symbiotic relationships are close and long-term interactions between different species in an ecosystem. These relationships can be beneficial, harmful, or neutral for the species involved. There are three main types of symbiotic relationships: mutualism, commensalism, and parasitism.

Mutualism

Mutualism is a symbiotic relationship in which both species benefit from the interaction. For example, the relationship between bees and flowers is mutualistic. Bees get nectar and pollen from flowers, which they use for food, while flowers are pollinated by the bees, allowing them to reproduce.

Commensalism

Commensalism is a symbiotic relationship in which one species benefits while the other is neither helped nor harmed. An example of commensalism is the relationship between barnacles and whales. Barnacles attach themselves to the skin of whales, gaining a place to live and feed, while the whales are unaffected by their presence.

Parasitism

Parasitism is a symbiotic relationship in which one species benefits at the expense of the other. The parasite benefits while the host is harmed. For instance, ticks and fleas are parasites that feed on the blood of other animals, causing harm to their hosts.
