'Ecosphere\r'

'This experiment tested the hide and how the bio-geochemical cycles inside it rely on each other. The worms relied on the purpose for shelter and the plant for group O. The Ecosphere overly evaluated limiting factors at heart an ecosystem because the bottle apply was a small, contained environment. For example, mavin of the troika worms had died because it got stuck between the plant and the side of the bottle. This is a limiting factor in terms of space: if thither was more space for the worm this would non take in happened.\r\nQuestion: If one producer and one consumer are to maintain a viable ecosystem in a bottle, how long go forth they survive?\r\nHypothesis: I bank the outcome of the experiment will be that all of the worms will survive and the plant will not. The worms will survive because I will be feeding them sawdust, their desired food, and they will get to cumulus of dirt to wiggle around in. The plant, however, will not survive because the plant’s resources are limited. The crud put into the ecosphere is not going to be changed out, therefrom the nutrients in it will diminish.\r\nBackground Information: The EcoSphere is a display of a working ecological system. duration it is beautiful to view, it also demonstrates the delicate balance of a closed ecosystem like the Earth. Contained within the completely sealed glass is a small variety of biota living in a filtered environment.\r\nThe EcoSphere contains some of the like essential elements that are found on our planet. The Earth is represented by the soil at the bottom. send packing is the light, which streams in each day. Finally, life: the worms, plant and microbes that extend in the EcoSphere.\r\nThe EcoSpheres biological cycle represents a bare(a) version of Earths own ecosystem. Light to engenderher with atomic number 6 dioxide in the water enables the plant to produce oxygen by photosynthesis. The worms breathe the oxygen in the ahir duration nibbling on the s awdust which is fed to them and bacteria. The bacteria break belt down the animal waste into nutrients, which the plant utilizes.\r\nThe worms and bacteria also give off carbon dioxide, which the plant over again use to produce oxygen. And so the cycle renews itself.\r\nMaterials: †one 1 liter coke bottle with top †one plant (bought from pet store) †3 exceedingly Worms †2 cups of soil †water †sunlight †sawdust (food) †scissors grip †duct tape †notebook to record entropy\r\nProcedure: All the materials were collected. thusly, a scissor was used to cut a half(prenominal) moon mold opening in the top of the bottle, approximately 1 inch below the cap. Next, half the soil was pored into the opening. Then the plant was placed into the soil, while poring the other half over the bottom of the plant to ensure straightlaced growing. After, 3 super worms were put into the Ecosphere with some sawdust. The EcoSphere was tape shut and placed on a windowsill with proficient sunlight exposure. Data was recorded at that bite and everyday, for 20 days, following.\r\nAnalysis: My hypothesis was very incorrect. 2 superworms ended up surviving, while the plant was wilting and struggling. One superworm died due to it getting stuck. Unable to get out, I assume it died of starvation or hypothermia because the worms fagged all of their time under the soil. I moot the plant wilted because it did not have equal space and oxygen inside of the EcoSphere.\r\nDuring the experiment, I believe the EcoSphere was knocked off the window. This could have hindered the plant’s growth also. The plant could have been up-rooted during the fall causing its deterioration.\r\n last: In conclusion, the EcoSphere project is important to our curriculum because it evaluates the bio-geochemical cycles, as well as tests limiting factors. An error make with this experiment was it being knocked over. This was very detrimental to the worms and could have been fatal for the plant.\r\n'
