Sample Coursework Paper on Food Web Diagram: Canada and Alaska Forests

There is a food chain for every organism. The food chain consists of a linear sequence made up of food web links, which start from a given species of organisms known as producers and extend up to a different type of species in the food web known as decomposers. Additionally, a food chain also depicts the relationship between different organisms, and their food.

In Alaska and Canada forests, the organisms that exist there include hares, foxes, coyotes, lynxs, great horned owls, vultures, and bacteria. These organisms entirely depend on each other in the form of a food chain. The primary producer is the grass. The hares are the primary consumers, whereby they are a prey to several organisms, such as the foxes, lynx, coyotes and the great horned owls. The vultures are the tertiary consumers to all the hares’ predators.

Benefit of the Biodiversity

The more diverse an ecosystem is, the more resilient it becomes. This implies that several species bearing different ecological functions can somewhat replace one another (Simon et al. 26). When a given species is destroyed to the extent of interfering with the food link in a diverse ecosystem, the organisms should be able to reorganize themselves for survival. Precisely, the more complex the food web, the more complex its links, the more resilient it becomes (Capra 18).

Potential Hazards Caused by Humans

Pollution is one of the environmental hazards brought about by human beings. In this case, environmental pollution on the primary producer, which is the grass may affect the survival means of the hares. As a result, the hares may not have an alternative, hence become depleted. This will affect the secondary consumers, which feed on hares. At the end, the entire niche will become depleted because the source of primary producers is not diversified.

Abiotic Factors Present in the Ecosystem

Abiotic factors refer to the non-living elements present in the ecosystem. In Canada and Alaska forests, the existing abiotic factors include sunlight, which is used by the producers (grass) to make food for them, soil that hosts the forest’s habitats, and rain that showers the entire plantation. Other organisms use rain for quenching their thirst.

Food Chains in the System

The food web in the forest ecosystem can be referred to as a Trophic level (Simon et al 34). This implies that there are three types of consumers and one primary producer. The primary producer is the grass whereas the primary consumers are the hares; secondary consumers consist of the lynx, coyotes, foxes, and great horned owls. The tertiary consumers are the vultures.

The ecosystem should be diverse to sustain all the organisms linked to the food chain. According to Capra (18), a complex interconnection of organisms calls for a complex food web that will prove to be resilient. The ecosystem will sustain the interconnected organisms even if others are depleted by means of diversifying. In a forested ecosystem, such as Canada and Alaska forests, it is expected that there should be a biodiverse ecosystem that will avoid depletion of animals. For instance, many animals rely on hares for food. In a case where hares become extinct, all the other organisms will be highly affected.
