Energy Flow Robert Green 1/9/15 SCI/275 Christina Kamnikar Energy Flow After reviewing figure 4-10 presented in chapter 4 of Environmental Science‚ it is easy to recognize the different trophic levels. Each trophic level shows how energy and biomass flow through a food chain however it is eventually lost as heat. These levels consist of: biomass of producers‚ those consumed‚ and those not consumed. The first trophic level has the producers which graze the food chain‚ grazers consist of the

This synopsis briefly explains the challenges faced by African countries with emerging oil and gas industries in bringing widespread economic advancement to their countries. Although‚ on the surface‚ the challenges appear straightforward‚ in essence they often prove to be very taxing and intractable. They are closely interrelated and‚ regrettably‚ have lingering consequences‚ which have come to be known as the ’resource curse’. At core the task facing these countries is how to ensure that the investment

Aggregation: Determine the lowest level at which observations are independent and then average scores of both the causal and outcome measures at that level. For instance‚ if children are nested in classrooms‚ which are nested in schools‚ make school the unit of analysis. Child is the lowest level and school is the highest level. If there are no school or classroom effect‚ then child would be the unit of analysis. If there were no school effects‚ but there were classroom effects‚ then classroom

1) Discuss the three energy systems that are responsible for the production of ATP. Adenosine triphosphate (ATP) is the immediately usable form of chemical energy use for muscular activity. It is stored in most cells‚ especially muscle cells. Other forms of chemical energy‚ such as that available from foods we eat must be transforming into ATP before they can be utilized by muscle cells . Human body cells generated ATP by three methods which are: I. ATP-PC system II. Glycolytic system
