Competition :: essays research papers

INTRODUCTIONCompetition occurs among any organisms living in a mutual habitat. Whether it is for food, water, shelter, or a mate, aspiration can be harmful or helpful to individually organism. There are two basic types of competition intraspecies and interspecific. These call refer to competition within a specific species and the competition mingled with different species, respectively. In this lab, we conducted 3 basic experiments. Our goal was to observe the cause of the competition in separately instance.The first one was to observe the intraspecies competition between the chaff plant species, the second was for the intraspecific competition between the mustard plant species. The third was the interspecific competition of the straw and mustard species together. The latter experiments data was divided into two sub themes of higher(prenominal) density and low density, for purposes of graphing Dewitt diagrams. Dewitt diagrams are a way of expressing % yield and integra lity productivity data so it can be evaluated and compared effectively. It has been noted that intraspecific competitions tend to be more intense than interspecific ones (Ciara, 1993). This is because members of the same species exact the same types and amounts of nutrients. When these similar species are in the same habitat with unbending resources, then they consequently have to "fight " for their needs. This is was basis for our hypothesis. We hypopthesized that the species that were involved with the interspecific competitions would have greater mathematical product (by ave. weight of grams) than their counterparts involved in the intraspecific competitions. Furthermore, we hypothesized that as the density of the intraspecific and interspecific competition species increased, then the production of the plants (by ave, weight in grams) would go down.MATERIALS AND METHODSSix weeks previous to the conductance of this lab, Biology 108 section,planted wheat and mustard plan ts according to table1 on page 3 of the Principles of Biology 108 Lab Manual . This table depicts all of the total pots and moment and type of seeds planted in the pots. It accounts for the experiments of the intraspecific competition and interspecific competition. Replicates of each pot were planted to add precision and more acceptable statistics. Therefore, there were 40 pots, that is, 20 treatments conducted twice(Ciara, 1993).Each Biology 108 section planted these pots and the data from every section was to be combined for an overall data sheet. Our group in section 6 had the role of planting 5 of the observational pots with the assigned number of wheat seeds or mustard seeds or both.
