How Does Food Web Affect Biodiversity?

Unit One Aha Thesis - Ecosystems Ecosystems are filled with abiotic and biotic factors. They both need the other for survival. Energy and nutrients flow through the trophic levels which helps ecosystems change and survive. Abiotic and Biotic Factors Abiotic and biotic factors are connected in many ways. One connection in Planet Earth was an antelope jumping into the water to be safe from the hunting dogs.

• Any refinements that were needed to achieve a balance of organisms in the ecosystem, and the associated effects of these refinements on population densities. Paragraph 1 The selected organisms to be involved in the food web simulation are Plant A, B and C, Herbivore A, B, C, Omnivores A, B and the top predator. In the simulation the top predator eats both the Omnivores and Herbivore B.

Leopold’s land pyramid describes the hierarchical dynamics of the biotic community. Based upon what we learned in class, a biotic community is the relationship between soil and animals. It is a sum of all the parts within the community. The pyramid represents layers within the biotic community. The bottom layer is the soil. A plant layer rests upon the soil layer, an insect layer lies atop the plants, a bird and rodent layer rests upon the insects. The pyramid works its way up the various animal groups until it finally comes to the peak layer, which consists of the lager carnivorous animals. Leopold places humans in the top layer.

The article Food Ark by Charles Siebert was an informative read that enticed a viewer, but possibly left them with too many questions. Many ideas and questions were left unfinished or unanswered making the reader dig deeper into other sources. Food Ark was based around the idea of the biodiversity in modern agriculture, or the lack thereof. They introduced the topic by providing the viewer with a few statistics that supported “food variety extinction”(Siebert).

I started simulation by testing all the possible outcomes from challenge 1 to 5 and used the best scenario from one simulation to the other step by step and drew the conclusion at the very end.

Simulation is a drug that reveals fellow Dauntless initiates’ biggest fears and inner solicitude. The simulation process is a ritual needed to provide the Dauntless leaders with information on the initiates. Simulation is portrayed as a test and is apart of surviving initiation. Something that exemplifies simulation is, “With a scream of frustration, I throw my hand forward and find a hole in the rock. My arms shake violently as I drag myself forward, and I pull my feet up under me before the wave can take me with it.

A true hero is one who is willing to commit body and soul to achieve a dream, discuss.

How many times did you run through this simulation? What did you learn each time? What were some of the biggest challenges?

Through out the course of history, those who were considered sinners were often out casted from the society. This is much the case with Hester Prynne in Nathaniel Hawthorne’s The Scarlet Letter. After a public trial, Hester is considered a sinner due to her birthing of a so called “devil child”. Hester is convicted to the life long bearing of a scarlet letter on her chest. The Scarlet Letter that Hester Prynne wears symbolizes the change in perception of sin through out the novel. Due to the revelations of the governor Winthrop and the reverend Dimmesdale, the way sin is perceived changes from one of shame to the idea that every one is a sinner in their own right.

Your coastal ecosystem includes food chains. What is a food chain? Give a visual and labelled example of the food chain associated to your eco system. A food chain shows how each living thing gets food to survive, and how the nutrients and energy are passed from creature to creature.

The population size, n, is increased from 10 in Simulation 1 to 50 in this simulation. The result from this simulation is smaller compared to simulation 1.Looking at the data, this means less population out of twenty were fixed and lost. An average of 5 in simulation 1 were fixed population and an average of 8 were populations that were lost. Compared to simulation 2, about 1 population was fixed in overall 5 runs shows a much lower fixed population. The number of population lost in simulation 2 is about one to two. The number of population lost in this simulation is much smaller than the average 8 population in simulation 1. This makes sense because when population size is larger, it is harder to fix or lose that population.

At this time, we learn contemporary foraging communities and

An easy, yet intelligible description by Arms, K. (2008), "Just as a car cannot run without fuel, an organism cannot survive without a constant supply of energy." (p. 125) There are multiple ways to trace the transfer of energy through an ecosystem such as food chains, food webs, and trophic levels. However, food webs are more practical given that they include more organisms and show multiple feeding relationships that are possible in an ecosystem.

Energy can be lost moving up in a food chain, this can limit the length of the chain. Food chain shows which animal eats what in a particular habitat. For e.g. grass seeds are eaten by a vole, which is eaten by a barn

Skip following is the specialty of finding somebody. A skip is a man who, for reasons unknown, leaves a given zone. Most skips in the long run leave either paper trails, verbal trails, or both. There are many explanations behind a man to skip, for example, marriage, separation, and retribution; getting away obligation; fatigue and dissatisfaction; amnesia; disobedience as well as enterprise; and running from the law. Skips can be partitioned into four fundamental gatherings: Unintentional skip - the individual is not purposefully stowing away but rather is undercover about his area; Intentional skip - the individual deliberately hides his area to stay away from banks or others;Marital skips - one gathering is overpowered by the weights
