Pigface Essay

Each step in a food chain is a “trophic level” because of the energy transfer between them which can be shown in energy pyramids. All of the energy that passes on originally comes from the sun before moving through the order of the trophic levels, which is from producers to primary consumers to secondary consumers, then eventually to tertiary consumers. Although, as one lifeform eats another for energy, only 10% transfers to the next level because that 90% is used to “carry out the functions of living, such as producing new cells, regulating body temperature, and moving,” or for other necessary tasks. These transfers through eating are important since they help maintain ecosystems like the Everglades Hardwood Hammock. (Arms,

Many times in a story what the main characters say can reflect their personality and lifestyle. This is shown effectively in the memorial epic by Paul Zindel, The Pigman. Throughout this stunningly truthful story, John and Lorraine consistently say things that show just what type of people they are.

This in turn would lead to more consumption at the top of the food chain, eliminating the predators to creatures at the lower end

The Year 10 geography field trip was an insightful experience into the workings and functioning of metropolitan coastlines here in South Australia. The day consisted of visiting various beaches in Adelaide that were influenced by some form of hard or soft engineering techniques that changed the natural processes of the beaches. What was evident from this trip was how much these beaches have been changed to an extent where it is unlikely that they will ever go back to the way they were prior to human settlement.

Provide a brief intro in which you identify the character whose life became brighter once the Pigman entered it:

Another ecosystem that I use each day is the nitrogen cycle. This is the process that consist of three

Cronulla is a beachside suburb in southern Sydney, it is located 34.0574° S, 151.1522° E which is 26 kilometres south of the Sydney CBD (see figure 2). It is governed by the Sutherland Shire Council. Cronulla’s coastal environment is on the Kurnell Peninsula, which is made up of a tombolo. A tombolo is a sand spit connecting a rocky outcrop or island to the mainland. So this forms a barrier between Botany Bay and Bate Bay. The two areas of study visited were Wanda Beach and the Greenhills Beach development.

To maintain life, organisms must be able to convert energy from one form to another. For example, in the process of photosynthesis, algae, plants, and photosynthetic prokaryotes use the energy from sunlight to convert carbon dioxide and water to glucose and oxygen (a waste product).

An ecosystem is a community of interacting organisms and their environment. If one of the organisms is disturbed, it can change the trophic cascade which is a sequence of impacts down the food chain. Hannibal supports this statement by writing “keeping these connections going ensures healthy, functioning ecosystems, which in turn support human life.”(578) An example of this is if all of the beavers died the other organisms would go somewhere else or die due because they no longer will have dams to support their ideal habitat.

tides. There are also many programs which help to ensure the stabilization of dunes, these include the planting of new vegetation to combat erosion, fencing and designated

Seahorses are secondary consumers. Secondary consumers are mainly carnivores, they eat other animals. Omnivores, who eat plants and animals are also called secondary consumers.

In the upper levels we see a number of fragmented bone which may suggest that they began to eat more from each animal killed. Perhaps animals became scarce therefore they began to explore the taste of bone marrow.

As the energy moves through the system, nutrients also travel through the levels of the food chain through the predator prey feeding cycle active in the food chain. To summarize the nutrients are cycled through the food web and the energy is not.

In this process, organic molecules, particularly sugars, are broken down to produce carbon dioxide and water, and energy is released.

In the ecosystem organisms rely on each other for food and protection. The Food chain is like a pyramid you have the producers, primary consumers, secondary consumers, tertiary consumers, and quaternary consumers. It’s an almost perfect balance and if any level were to just stop existing then the food chain would be destroyed. An example of organisms relying on others is an issue of isle royale were the wolves and moose population are in jeopardy. This relationship is important because without the other animal the population would die.
