Summary:
An Ecosystem is the interaction of living and non-living organisms, known as biotic and abiotic things. Normally, an ecosystem can stay stable since there is an equal amount of everything. However, it can go unstable (sometimes permanently) for several reasons. One can be that there is a lack of one or more organisms. For example, if the fox population in a fox-rabbit-grass ecosystem disappeared decreased significantly, the rabbit population would increase since there is no fox eating the rabbits, making the grass population decrease since all the rabbits are eating it. Another way that an ecosystem can go unstable is if an invasive species (a non-native species) is introduced into the ecosystems. It can eat the prey faster making the predator population decrease, or can make the producer population go extinct, killing the energy pyramid.
Backwards Looking - How much did you know about the subject before we started?:
I knew most of the things learned in this unit. I knew that an ecosystem had an energy pyramid with the apex predators at the top, the primary, secondary and tertiary consumers in the middle, and the producers (plants) at the bottom of the pyramid. At the very bottom of the pyramid had decomposers which turned the dead organisms into nutrients which went into the soil for the plants to use. I also knew the effects of an unbalanced ecosystem if a certain population increased or decreased. For example, I knew that if the primary consumer population increased, then the producer population would decrease. Before I started on the ecosystems unit, I also knew a little bit about invasive species and how they would affect the non-native ecosystem it entered.
Inward Looking - How do you feel about this piece of work? What parts of it do you particularly like? Dislike? Why? What did/do you enjoy about this piece or work?:
I thought that this project could have been a lot better than it was. The main thing that I thought could have been better was the execution of the information I had gathered. The part of this project I personally liked was the brainstorming and research since I could explore which invasive species I could present. The part that I dislike the most was making the actual poster, since although the information I gathered sufficed, I thought that I could have added more graphics and made the poster much more neater. I also thought that the presentation could have been better since I was unprepared for it and had no script.
Outward Looking - Did you do your work the way other people did theirs? In what ways did you do it differently? In what ways was your work or process similar?
Many of the presentations I saw had work that was online/on a device. However, the work that I presented was a physical poster talking about my invasive species. Also, some groups didn't do the invasive species project. Some groups talked about an endangered species. What all groups had in common, I believe, was the work process. The first thing that all of us did was that each member in a group gathered information on three invasive/endangered species and then all members in the team agreed on one organism to focus on. Then each group worked on specialist sheets that when filled out, would contain certain information about an endangered species. For example, the ecologist sheet showed information about the origins of the invasive species and the impact, while the biologist sheet showed the basic information and the characteristics of the invasive species. Once the specialist sheets were filled out, it was essentially a checklist of the information that needed to be presented.
Forward Looking - What would you change if you had a chance to do this piece over again?:
If I were to do the invasive species project all over again, I would change a few things. The first change is to change the invasive species I was researching, since the one that I initially researched (Asiatic Citrus Canker) had some information that was difficult to find such as the organizations working to stop it. I would also change the presentation from being a physical poster to a virtual poster online, since it is easier to organize online. The final thing that I would change is the presentation. Next time, I would prepare a script on what I was going to say since in this project I didn't have one. These changes that I would make if there was a revision would make the project much better.
