Symbiotic Relationships What is Commensalism? An association between two organisms in which one benefits and the other derives neither benefit nor harm. What is Mutualism? Symbiosis that is beneficial to both organisms involved. What is Parasitism? relationship between two species of plants or animals in which one benefits at the expense of the other, sometimes without killing it.

Cattle Egret Ecosystem The cattle egret is the most terrestrial heron, being well-adapted to many diverse terrestrial and aquatic ecosystems. Though it does not depend on aquatic habitats to survive, it does make frequent use of them, even when they are not close to livestock-grazing areas. It is also well-adapted to urban areas. In its breeding range, which is similar to its winter range, it often nests in heronries established by native ardeids.

Livestock Ecosystem They are apart of the terrestrial ecosystem because they are apart of a community of organisms and their environment that occurs on the land masses of continents and islands.

Description of Interaction The cattle egret is a common species of heron that is found in most regions of the world, and is mostly seen moving along with herds of cattle. This bird moves about in the pastures, and follows livestock such as cattle and horses. The cattle egret eats up the insects hiding under vegetation close to the grounds, which get stirred up when the cattle walk through them. In this interaction, the cattle egret benefits by eating up the insects, but the livestock remains completely unaffected.
