Eco-Column Lab
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 of possible things to add to the decomposition chamber are leaves and compost. Lastly, the terrestrial chamber contains a small plant or seed as well as soil and/or fertilizer or mulch. The purpose of our making the eco-columns is to observe the effect of the manipulated variable on the dependent variable; more specifically, what is the effect of fertilizer in the terrestrial chamber on the growth of the golden nesaea in the aquatic chamber? One eco-column will contain fertilizer in the terrestrial and the other eco-column will have no fertilizer in the terrestrial chamber. Our hypothesis is that the fertilizer in the terrestrial chamber will increase the growth of the golden nesaea in the aquatic chamber. The fertilizer in the …show more content…
This carbon is combined with other elements in intricate ways to form organic molecules significant to life.The carbon is later passed to animals who consume plants. When plants and animals die, the majority of their carbon is given back to the atmosphere as the organisms begin to decompose. Occasionally, there will be a plant or animal does not decompose immediately. Their bodies are confined in locations where decomposition cannot occur. This typically happens at the bottom of seas and oceans where the lifeforms become buried by

    2. Five variables that should be controlled during the experiment is the amount of sunlight, room temperature, amount of water, the time of day the plant is watered and the certain type of plant. To make sure the plants get the same amount of sunlight, make sure to put them both in the same spot so that one plant doesn’t get more sunlight than the other. To make sure they both stay in the same room temperature, put them both in the same room. With the amount of water come up with a measurement, and then make sure you give both plants that amount. Pick out a time of day for the plants to get watered make sure you water one earlier than the other since it is part of your hypothesis that they grow faster when watered in the morning. Finally, make sure that…

    The dependent variable is the Brassica Rapa and it is depending on the temperature. Before the experiment took place, all plants were in 22 degrees Celsius for three weeks to grow to the preferred maturity. They were then taken out and pollinated. After pollination the plants were set in separate temperatures to mature for another two weeks. After the two weeks were over, the plants were taken out of their temperatures and soil to determine maturity and productivity. To do so, the plants were weighed, the length was measured, the pods were counted, and the amounts of mature seeds were counted as…

    Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process, e.g., due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements may also become available for use by the primary producers (i.e., plants and phototropic microorganisms). Decomposition is an important step in the food chain and contributes to the nutrient cycling within an ecosystem. Most of the organic matter in an ecosystem ultimately passes through the decomposer subsystem.…

    1. The framers created a bicameral legislature because of the Great Compromise at the Constitutional Convention which stated that one house’s representation will be based on a state’s population and the other would have equal representation. Another reason is that it would help prevent tyranny because both houses can “check” each other to make sure one does not get to powerful. One power unique to the House of Representatives is that revenue bills must originate from the House; the framers gave this power to the House because the House of Representatives is more representative of the entire population than the Senate is. One power unique to the Senate is that they are the ones that try the President for impeachment; the framers gave this power to the Senate because they reflect the state’s interests and also because they are more “mature” than the House of Representatives since the required age is higher.…

    Carbon is an element essential to all living things on Earth. It undergoes two cycles that are necessary to stabilize the environment: the biological carbon cycle and the geological carbon cycle. In the biological carbon cycle, carbon is absorbed in plants and the inorganic carbon is converted to its biological form through photosynthesis via plants and phytoplankton ("Carbon cycle," 2008). During respiration, carbon dioxide reenters the air after being broken down for energy (ATP) carbon dioxide gas. Carbon that remains in the oceans sink are buried into the earth's crust. When humans extract oil and coal for energy usage the byproduct carbon dioxide is released affecting the geological carbon cycle. The biological cycle is affected in two ways. When forests are cleared for land usage, the burning causes a release in carbon dioxide and the cleared land can no longer assist in the process of photosynthesis or the removal of carbon dioxide from the atmosphere ("Carbon cycle," 2008).…
