POP BOTTLE ECOSYSTEMYou will be creating a closed ecosystem inside a 2L bottle with the goal that it is in ecological balance and self-sustaining. You will be formulating a hypothesis in regards to how you think your ecosystem will develop over time. In addition, you will be keeping a journal which outlines the changes you observed on a weekly basis. This will be done in two parts. Part 1 - create your ecosystem and grow producersPart 2 - introduce consumers and seal the ecosystemYou will keep a journal (duotang or notebook) to document each decision and observation you make during the semester. See the handout on how to write a scientific journal for guidance. Each group will need to submit ONE journal.Part 1:Follow the instructions to create your ecosystem (separate handout) Note:We will get “sludge”, aquatic plants, and distilled water from the lab upstairsBelow is a list of primary producers. Choose which you want to have in your ecosystem. Seed Mix (Brocolli, red clover, radish, and alfalfa) Assorted seeds (lettuce, microgreens, Cress) Grass seedDuckweed (aquatic) Elodea (aquatic)Part 2: Choose some (minimum 2, maximum 4) consumers to add to your ecosystem and research what they need to survive. Does your ecosystem supply what they need? Why did you choose these consumers? (Write everything in your journal). You need to start your journal with a diagram of your ecosystem and create a hypothesis in regards to how your ecosystem will change over time. You will make observations on a daily basis.Below is a list of consumers I will be providing (you can choose to bring your own – insects only)House Cricket (Acheta domesticus) Indian Walking stick (Carausius morosus)Snail (various species)Mealworm beetle larva (Tenebrio molitor)Sowbug (Armadillidium vulgare) – common household insect that you can bring ECOSYSTEM IN A BOTTLE CONSTRUCTIONMaterials: two 2-liter soda bottles, 2 bottle caps, cotton string, water, soil, plants and plants. 49530008445500Procedure: Step 1 – remove label from 2-liter bottle. On bottle #1, cut 2 cm below shoulder to produce component “A,” a shallow funnel top and “C” a deep reservoir. 28181307493000Step 2 – Poke a 1 cm hole in one bottle cap 462026030861000Step 3 – Cut Bottle #2, 1 cm below hip to produce component “B” a deep funnel unit with hip taper471868512763500Step 4 – Fill reservoir with water. To be effective, the wick should run up into soil, not be plastered along a side of the bottle. For better drainage, place a layer of gravel, sand, or vermiculite in the bottom of the soil unit.Step 5 – Fill the top unit of your column with soil you collect, or with potting soil. Add the plants or seeds. Step 6 – fill the lower aquatic unit with distilled water, or water from a pond, lake, puddle or fish tank. ................
