An eco-column is used to model an ecosystem on a smaller scale. The purpose of an eco-column is to examine how an actual ecosystem would respond to different conditions. Eco-columns typically have three chambers: the aquatic chamber‚ decomposition chamber‚ and terrestrial chamber. The aquatic chamber contains water and an aquatic plant‚ and it is at the bottom of the eco-column. The decomposition chamber contains items that will work as decomposers and as a possible catalyst for plant growth. Examples

The materials we used for this project were the fruits and vegetables and an amp meter to measure the current flow in them. We learned the difference between electrical charge and conductivity. We measured the electrical charge first and the conductivity second. First‚ we looked for current flow in each of the fruits and vegetables using the micro amp scale on the meter. Second‚

Question 1: Assume that Econoland produces haircuts and shirts with inputs of labor. Econoland has 1000 hours of labor available. A haircut requires ½ hour of labor‚ while a shirt requires 5 hours of labor. Construct Econolands PPF. Answer 1: To construct Econolands Production Possibility Frontier (PPF) we first need to understand what is a PPF. A production possibilities frontier (PPF) is a graph showing the different quantities of two goods that an economy can efficiently produce with limited

An Economist ’s Perspective He was sent to Oxford by the age of twelve‚ to study law as his father did. In 1748 Jeremy Bentham was born to a London attorney and his wife. However‚ Bentham ’s attention turned to law reform while at college and was opposed to practicing law (The Concise Encyclopedia of Economics‚ 2008). His interests became devoted to studying and writing‚ many times spending several hours a day writing. Even though Bentham wrote a great deal in his lifespan‚ several of his works

To be honest‚ I never really have put much thought into the environment and how every little thing we do affects it in some way. Coming in to college and taking my environmental biology class and now watching the documentary in this class has opened my eyes to some realities about the world we live in today‚ such as‚ half of the forests that originally covered 46% of the Earth’s land surface are gone. Only one-fifth of the Earth’s original forests remain pristine and undisturbed. Furthermore 60%

1) Identify the change in total revenue (the marginal revenue) from the fourth shirt per day. What price reduction was necessary to sell four rather than three shirts? Marginal revenue for the fourth shirt is $41 even though it price is $44. Price reduction is $1 which is from $45 to $44. 2) What is the change in total revenue from lowering the price to sell seven rather than six shirts in each color each day? The change in total revenue from selling seventh shirts rather than sixth shirts is

Current and Non-current Assets Without assets‚ businesses could not function. In order to show how much a business owns assets are used in accounting to clearly define the positive side of a balance sheet. Current and non-current assets are not only cash‚ but also monies which will turn into cash in the future. This includes receivables‚ properties‚ work in progress and buildings. This paper will define current and non-current assets‚ differentiate between the two‚ the order of liquidity and

Eco-Industrial Parks: The Case for Private Planning Industrial ecologists are championing eco-industrial parks or EIPs as tools for pursuing sustainable development. An EIP is a community of companies located in one region that exchange and make use of each other’s by-products or energy. Among the best known is Kalundborg‚ Denmark‚ a city in which the major industries and the local government trade their waste streams and energy resources. Many commentators see Kalundborg as a model that should
