Option 1: Food Webs Case Study Explain the theory in your own words based on the case study and suggested readings. A food web is a type of graph that depicts the relationship between the prey and the predators‚ also known as a system of food chains and how one another are related. This can be better explained as a connection in a community. Food webs are important because it is a direct illustration of the relationships among certain species within a certain community. Right away the graph

DiffDifferent Ways of Looking at Food The Omnivore’s Dilemma‚ by Michael Pollan‚ attempts to figure out how such a simple question as‚ “What should we have for dinner?” (Pollan 1)‚ turned out to be so complicated such that we need investigative journalists to tell us what is in our food. To do so‚ he went on a journey to follow all three food chains that sustain us today: the industrial‚ the organic‚ and the hunter-gatherer back to their origins. Although these journeys may have led to very different

The Everglades reaches from central Florida‚ near Orlando‚ all the way south to Florida Bay (National Wildlife Federation‚ 1996-2013). During the wet season‚ Lake Okeechobee overflows‚ releasing water into a slow moving‚ shallow river. The river is mostly saw-grass marsh. The Everglades is an ecosystem that hosts a large diversity

------------------------------------------------- Food web From Wikipedia‚ the free encyclopedia A freshwater aquatic and terrestrial food web. A food web (or food cycle) depicts feeding connections (what eats what) in an ecological communityand hence is also referred to as a consumer-resource system. Ecologists can broadly lump all life forms into one of two categories called trophic levels: 1) the autotrophs‚ and 2) the heterotrophs. To maintaintheir bodies‚ grow‚ develop‚ and to reproduce

Human Influences in a Food Web The temperate rainforest biome (specific to America) is most commonly recognised by its large and tall trees‚ non-seasonal vegetation‚ heavy rainfall and dense humidity. Temperatures rarely drop below freezing and irregularly exceed 27o C. Rainfall usually ranges from 127-165cm a year‚ with some rainforests occasionally receiving more [1]. At the first trophic level the producers are found‚ including: plants‚ flowers‚ seeds‚ nuts and fruit. The first order consumers

2/4/12 Efficiency of Food Production Systems Objective 1: Compare and Contrast Aquatic and Terrestrial Systems Humans depend on food systems in order to survive. These food systems follow the same paths and rules as food chains. Food chains follow the first and second laws of thermodynamics. Energy is lost as it passes through food chain from one trophic level to the next due to decreases in food. In turn there will be fewer organisms at trophic levels as they increase. Food systems are dependent

nutritious food has become an issue of interest to the residents of Colorado. According to the Nutrition Digest‚ ‘food deserts’ are “parts of the country vapid of fresh fruit‚ vegetables‚ and other healthful whole foods‚ usually found in impoverished areas” (Gallagher). Areas of Colorado such as this exist in largely rural and urban or low-income neighborhoods throughout the state. In these underserved communities‚ the issue lies with the ability to realistically travel to get fresh food and the‚

our nation. One factor that deserves to be studied more is the phenomenon of food deserts. There are many ways to define a food desert‚ but a common way to define it is as a low-income census tract where a great portion of its residents have low-access to a supermarket or a large grocery store. This phenomenon occurs nationwide and is an issue that should be acknowledged and dealt with. Currently however‚ food deserts is a phenomenon that has yet to gain the proper acknowledge for the threatening
