12/1 - 12/3: As we begin our biosphere construction, ive made some final conclusions about Moore Park and looking at it as a biosphere. Yesterday, we took a closer look into our biosphere when we tested dissolved oxygen levels and Ph. Part of our experiment prior to putting the shrimp in was to leave one jar open while the other sealed. The sealed jar showed a dissolved oxygen level of 8.1 while the open jar was 8.9. I looked back at my notes and saw that the dissolved oxygen level of Moore Park pond was 7.6 Dissolved oxygen dissolves into the water from two sources, the atmosphere and the plants living in it. So the sunlight that covers so much of the pond is allowing the summerged plants and vegetation to go through photosynthesis. Photosynthesis produces oxygen, so oxygen levels should be much higher. So in conclusion, it is paramount that our biospheres be in natural sunlight in order to have good oxygen levels, and overall establish a constant, stable, environment for our shrimp.
What about decomposition?
What is it?
Where does it occur?
In what ways can we apply this to our environment and other living systems?
My definition: the process that bacteria and other organic matter break down things (like food, plants and animals) over time. (This is my definition, not something copy pasted that is showed in Koke's profile).
Decomposition Experiment
Purpose - To look at this as a means to compare and build our understandings of ecosytems and the interactions that occur among them.
For our experiment we decided to do something simple yet would give us good results. We decided to look at moisture and see if it can slow or speed up decomp. In one of our jars that had a large leaf and about an inch of water on the bottom, we noticed the water changing color and collecting sediment, probably decomposed matter off the leaf. So we
