Mutualism of Rhinz Essay -- Biology, Symbiosis

Symbiosis refers to a relationship in nature, between ii organisms. It commode exist in any of 3 forms. These are usualism, commensalism, and parasitism. distributively of these are distinct symbiotic systems in which at least unmatchable of the organisms improvements from the relationship. In a mutual relationship, both organisms will benefit in mavin way or another. In a commensal relationship, one(a) organism will benefit from the partnership, while the other will not be hurt or benefitted. Finally, in a epenthetic relationship, one organism will benefit from the partnership while the other organism will be harmed or even killed. The focus of this paper is mutual symbiosis found in nature (Patek, 2011). Symbiotic mutualism is a partnership in which both organisms will benefit from the relationship. This relationship just to both organisms thus is beneficial to the ecosystem, indirectly. An example of this relationship, found in nature, is that of rhizobia and leguminous plants. In this relationship, both the genus Rhizobium and the legume on which it strives, benefit, in that the legume is enriched with due north and amino acids by the rhizobium, while the rhizobium is given the important organic fertilizer molecules which act as an energy source for the bacteria (Kiers et. Al., 2003). The nitrogen in this reaction is a very important nutrient, as it is a drive force of many photosynthetic processes. This process is carried out by the rhizobium bacteria attaching to a nodule on the root hair of the legume plant, taking nitrogen from the air and converting it to a form usable by plants (NH4) utilizing the enzyme nitrogenase, and in return receive the growth molecules it requires (Denison & Kiers, 2004). Both organisms do benefit from the partnership they share however, thi... ...c relationship with legume roots. However, this symbiotic relationship, in specific, can exist in one of two forms, either mutual or parasitic. Although the strand whic h exhibits mutualism most prominent among rhizobial populations, the parasitic strand does exist, however is slowly being eradicated by the constantly evolving legumes. Researchers have studied the different strands of the bacteria, and have attempted to conclude on the efficiency of both recess strands. Each has concluded that although the parasitic strands have much less consummation to do to obtain the essential molecules to aid it in growth, it obtains a importantly smaller amount of the growth molecules, if any. This is because through evolutionary pathways of the legume roots, the parasitic strand is selected against, and the legume favors the more hard-working mutual strand of the rhizobium bacteria.
