David Flint Honors Bio Flow of Energy a. Why is phytoplankton found at the bottom of each of the 3 pyramids?
Phytoplankton are found at the bottom of the three triangle because they are the smallest things in that food chain. There is nothing that they can eat and they are easy pray for all the other bigger predators. b. What do you think “trophic levels” are?
A tropic level is a rating of how much energy they provide and how much energy they need.
With 1 being the lowest amount c. What is the correlation between trophic level and available energy units? Provide a reasonable explanation for this pattern.
The phytoplankton need the least amount of energy there for they provide the least amount of energy while something like a tuna needs a large amount of energy so it takes a smaller amount of them to reach a certain amount of energy. The patter could be that the phytoplankton are always at the bottom with a thousand but something like tuna is near the top with a small number. d. Which pyramid has the most available energy left at the top? Provide a reasonable explanation for this pattern.
The second level harvesting has the most energy at the top because there are a direct amount of plankton going straight to the fish. These would have the most energy because they aren't competing with other fish to eat the plankton. e. About what percent of energy is available from one trophic level to the next?
It depends on how efficient the fish are at eating all of the smaller fish. The smallest chart is
20% then it just decreases by 5% every time a new predator is added.

a. Where is atmospheric nitrogen’s next move in the cycle?
The nitrogen makes it way, one way or another, back into the soil. b. What do you think nitrogen “fixation”

Energy Losses In Pipe Flows

An Essay on Energy Losses in Pipe Flows The transportation of fluids is key in the world we live in today. Whether it is the movement of sewage waste from the home to treatment plants, the transit of the worlds most most valuable commodity in crude and petroleum product pipelines, to the transportation of water in homes, pipe systems are integral in civilization. In order to ensure the efficient, cost effective and required volume of flow of fluids in theses systems, the…

Essay about Energy Flow

Energy Flow Sarah Wegner SCI/275 July 10, 2015 Sandra Babuka Energy Flow According to the text, the feeding level on the food chain is considered the trophic level. At the base of the food chain is the producers. The second level consists of the first-order consumers known as the gazers. The carnivores that feed on the gazers are on the third trophic level. What is meant by this statement is that, the shorter the food chain is the more food there is for availability at the upper level. In pyramid…

Energy Flow Among Organisms of a Food Chain in the Desert Essay

Diagram: The plants in the desert survive off of the sunlight and rainwater. Plants are producers and depend on the sun for their energy. The three major producers in the desert are cacti, yuccas, and creosote bushes. Consumers in the desert are the organisms that depend on plants for their source of energy. The major consumers in the desert are lizards, birds, locusts, kangaroo rats, and beetles. Decomposers of the desert biome are organisms that break down dead animals…

Essay about thermo report

Internal Combustion Engine and measure the different energy contributions to it. The engine itself can be treated as a thermodynamic system. The energy contribution which are not possible to measure can be estimated using a basic steady flow energy equation. The type of internal combustion engine used for the experiment was a Petter four stroke diesel engine. Objectives- Using the measurements of the different energy contributions to find out how the energy put into a diesel engine is used and where in…

Essay about Science -Enegy

Science assignment 1. Draw an energy chain to show energy transforms in an eclectic kettle. Electrical potential energy – electrical energy - heat energy – kinetic energy – sound energy – elastic energy. 2. Explain how an electric current provides energy for electric appliances. Electric lights, refrigerators, TV and stereos need a steady source of electric energy comes from an electric current, which is the flow change through a conductor. In solids, the flowing charges are electrons…

Advantages Of Wind Energy

develop alternative energy source. Our current rate of fossil fuel usage will lead to energy crises in this century. In order to avoid energy crises many companies in the energy industry are inventing new ways of extracting energy from renewable resources. Wind energy is basically the kinetic energy of moving wind. It is renewable source & thus having far reaching economic value. The use of wind energy as an auxiliary source of energy is the at most need of modern society. Wind energy is harnessed by…

Sediment Transport and Ritter et. Al Essay

well as flows induced by gravity and finally glaciers. (Reading, 1996) The strength with which these factors operate depends on the ability of a landscape to resist the stress that is being put on it as well as the energy of the stress factor which can come from climatic conditions, tectonics and various other influences. (Holden, 2005) As mentioned above two main mechanisms which control the transport of sediment can be identified, one of them is called current flow and the other mass flow. Current…

Insulation Lab Report

insulation experiment, we were studying how insulation can affect the temperature and energy in the house/box that we experimented with. As a class and in our groups, we were looking at how the heat flow was affected by the insulation in our box by warming up and cooling down the box. In the experiment, we were seeing how the insulation prevented the rate of heat flow from being strong. Also, we were studying how the energy was flowing while the temperatures were raising and lowering. We studied how warming…
