Evidence: 

Reasoning: The game is an example because if you took away the decomposer slide, you have emideately affected the entire game scenes you can eventually get to any slide from the decomposer slide. The eco columns is an example because if you take away the decomposer layer, then there would be no nutritions for the layer below. The aquatic layer would die and water would not feed the layer at the top. Lastly, matter can not be made or destroyed, this means that the matter from dead animals would just lie there building up more and more corpus.

Without Andy decomposers there would be no cycle of nutrients. Because of this, the nutrients will not be cycled through the animals and because of the lack of paramount nutrients, there will be total collapse in all food webs, and Earth would be lifeless. 

Evidence

Reasoning:

Without their small but powerful decomposers the whole food chain will collapse because there will be no cycle of nutrients. The earthworms in my decomposition layer showed what a vital impact they have and when they do their job by spreading the nutrient it will allow other plants and animals thrive even if they are not directly using them because when the decomposer give off nutrients to an animal or plant that animals or plant will help the ecosystem. In easy terms the decompose rs help the ones who help the one who help the one and so on till the decompose rs has to decompose again. Through the nitrogen cycle it showed us how reliant the ecosystem is on the nutrients to keep their ecosystem in cheek. Thanks to the decompose rs we are here and so is every other plant and animal. 

Decomposition Scientific Explanation

Claim: 

In the aftermath of the removal of decomposers, the absence of bacteria, fungi, and detritivores, will result in the immediate pileup of dead organisms, but will eventually lead to the depletion of all living organisms and the end of all biogeochemical cycles.  

Evidence:

1. Decomposition in my Eco-Column was present.  I know this because my orange was broken down.

2. Nitrogen Cycle Game

3.“Nutrients are nonliving matter that are crucial to the growth of living organisms.

When organisms die, decomposers break them down into nutrients and gases so that they can be used by other organisms such as plants.”

Reasoning:

In the aftermath of the removal of decomposers, the absence of bacteria, fungi, and detritivores, will result in the immediate pileup of dead organisms, but will eventually lead to the depletion of all living organisms and the end of all biogeochemical cycles.  When nitrogen from the atmosphere enters the soil, it undergoes nitrogen fixation, resulting in Ammonia NH3, and nitrification, resulting in Nitrite (NO2) and Nitrate (NO3).  After this stage, the processed nitrogen will enter plants.  Although decomposers will recycle the nitrogen back into the soil when the plant dies through ammonification, this system can be replenished by the atmospheric nitrogen for hundreds of years without decomposers.  This proves that the nitrogen cycle won’t be critically affected by an absence of decomposers in the near future, but a pile up of dead organisms would be observed.  The nitrogen cycle game results in this same conclusion when the nitrogen atom got stuck in the dead plant or animal slide.  During the phosphorus cycle, when a plant dies, the phosphorus it contains will be recycled back into the soil.  Here, the phosphorus will either be reabsorbed by another plant, or  leaching or mixing with water can occur, and the phosphorus will eventually end up in the bottom of a lake or ocean.  The phosphorus will pile up and be cemented, forming phosphate containing sedimentary rocks including limestone and mudstone.  As time passes, geologic uplift and weathering will cause these rocks to release phosphate ions, which are available to plants.  This proves that the phosphorus cycle can replenish itself for a while.  Carbon cycles through the carbon cycle in the form of carbon dioxide and other inorganic and organic compounds.  Carbon, a vital ingredient of photosynthesis enters plants as carbon dioxide along with water and sunlight.  The result of photosynthesis is glucose and oxygen.  Animals receive carbon by eating plants and receive oxygen by breathing the oxygen plants released.  Plants can then reuse the carbon dioxide the animal breathed out.  Decomposers come into play when the plant or animal dies.  When this happens, the decomposer will eat the organic matter and release carbon dioxide (an inorganic form of carbon).  This proves that the carbon cycle can still run for a few years after decomposers are removed from this planet.  For all of these biogeochemical cycles, I have mentioned that they can run for a while after the decomposers are terminated from this planet.  After this set amount of time, all biogeochemical cycles will collapse, resulting in the depletion of all organisms on this planet.  In a small ecosystem such as an eco-column, all biogeochemical cycles will shut down immediately because the decomposition layer cannot produce any carbon dioxide and nitrogen.  All these pieces of evidence prove that in the aftermath of the removal of decomposers, the absence of bacteria, fungi, and detritivores, will result in the immediate pileup of dead organisms, but will eventually lead to the depletion of all living organisms and the end to all biogeochemical cycles.
