Food Web Case Study

                             In this case study I will be writing about the food web. This is a single ecosystem all the food chains consisted in a food web network. People that are inhabit in an ecosystem is part of more than one big food chain. The grand process moves on through our ecosystem each food chain is like one possible network path that energy & nutrients may intake. This system is all interconnected as well as overlapping food chains contain many organisms that take place within various niches because their resources are available for their habitat.  There are all types of organisms within the food chain or food web are grouped into categories which are called trophic levels. This case study, we will use the food web as a directed graph to model the relationship between predators as well as prey in an ecological community and the use of graph to visually break down the important parameters that consider a competition for ecological surroundings for organisms.

                      This ecological community graph will display an apex for each organism in a trophic level and a direct border from the apex visually explaining individual A to the apex illustrating individual B, and however, the path continues if ( A preys on B as a result). Within this particular graph, the salamander, toad, snake, robin, raccoon, grasshopper, & the fox were chosen for a group of seven species in which the results displayed competition among one another. Again, if there is a common prey within this the species will compete for the kill two species will compete for the kill. The ecological graph displays the vertex of the fox & raccoon since the robin is the most common prey. As for vertex of the snake & raccoon displays data that both species compete for their common prey the grasshopper. Next the vertex of salamander and the robin do not compete with one another since they do not share or have same prey. This will have a result of a simple food web clearly displays a competition relation.

                       Which means different species will compete with one another to catch a most common prey to eat than those who do not share a most common prey will not compete together. Various species of all sorts inhabit niches in which it is the practical relationship of an organism to its substantial & biotic domain. Resources that are referred to in terms of factors include the weather like the moisture, temperature, as well as degree of acidity, amounts of nutrients, and so on. At best we can consider that these subjects to resistance for a species defines a region on a graph in n-dimensional Euclidean space where as n is the number of factors the region is called the ecological niche of the species in question according to Roberts in Discrete Mathematical Models with applications to social. Speaking in simple terms two different species will not have the same ecological niches although, they will compete if their ecological niches have open network paths through their intersection. However we all should consider that these niches are certainly multidimensional because they include a wide variety of these aspects of the environment. Food web organisms are grouped into categories called trophic levels. The trophic levels were a way to measure the estimation of an organism within the food web. It is a helpful method to understand the complexity and diversity of the food web because most of the organisms on the tropic status have many complications of own purpose.
