The decomposition level is on the top so that when the water cycle runs back down, it will carry down the nutrients from the soil on the decomposition level to the other levels. The components for each section, aquatic, terrestrial, and decomposition, were collected and added accordingly.

These organisms were important because they all helped the energy flow through the ecosystem. The producers were the elodea, which were the source of energy for the environment that they absorbed from the sun.
The Eco-Column was constructed out of four 2 liter soda bottles and one large water jug. The rest of the column was constructed from carefully cut two liter soda bottles.
This is why the leaf litter was so important. These levels were placed in this order to make sure for successful function.
This made the Eco-Column not a completely closed system, being sealed the majority of the time except for our testing periods.
The leaf litter would be considered producers even though they were already dead. The organisms and materials present in this level were: They were producers because this is where the primary consumers got their energy.
This means that all of the chemicals in the eco-column stay there and may just change form. These factors include food chains and chemical and nutrient cycles. Aquatic Level The organisms present in this level included mosquito fish, river snails, and elodea.
The base was made from a large water jug and housed the aquatic portion of the eco-column. In this zone, the organisms and materials present were soil and grass. The snails were added to keep the tank relatively clean, as they were bottom feeders. The twigs were mainly for the spiders to support their webs on, the dirt for the grass and the worms to bury in, and the rocks were for an insects such as the centipede to hide under.
They were eaten by the first level consumers, or the fish. The water was important because it allowed the water system in the eco-column to occur. The order of the levels in our column went from decomposition on top, terrestrial below it, and the aquatic level on the bottom.
This ensured that the ecosystem was closed from outside influence. The aquatic zone needed to be on the bottom for obvious reasons that if it were above another level, it would need to be sealed off so it would not leak into lower levels, but that would then cut off the water cycle.
The salamander was a primary consumer as it ate the leaf litter. This eco-system is a closed system because it is not able to interact with the outside environment. The materials providing an environment for these organisms are twigs, rocks, and dirt. No other materials were added to this level aside from the water.
The ants, centipedes, and worms all were primary consumers as they all ate the leaf litter.The Bottled Ecosystem Annotation Students break up into groups and conduct Lab activity as outlined in student handout.
Circulate classroom, aid students in set-up, answer questions. Step 3: Review, 20 minutes Add precipitation to the bottle ecosystem once it is assembled. Record the volume of water. Procedure: Cut top off 2 liter bottle and bottom off another.
Fill the one without a top with water and put a plant, 1 fish, and 2 snails in water. Put a rag through the top of other bottle and pile with graphite (rocks). Eco Bottle Lab Report. Topics: United States Banana Oil Lab Report Jesse Bradford 7/10/14 MTWR Section Introduction In the banana oil lab we began with isopentyl alcohol + acetic acid isopentyl acetate + Water.
We needed for this experiment a hot plate, clamps, pipette, 5mL.
This ecosystems lab allows your students to create and carry out a hands-on, engaging experiment on how humans affect our environment. It utilizes the steps in the scientific method to scaffold learning and allow your students to come to a conclusion based on findings that are tangible.4/5(39).

Eco-Column Lab Report Procedure Abstract/Introduction The purpose of this eco-column activity was for my group and I to have a more in depth understanding of how biogeochemical cycles and different populations contribute to the health of their habitat in the real world and see how everything is connected.Download
