Lab #1 Biological life at AU
The purpose of this lab was to observe an ecosystem. I was also required to collect a sample from the environment in that ecosystem. By observing a specific ecosystem, I am able to see the organisms and their niches in the community.
In this experiment, my partners and I were assigned a 20 m x 20 m transect (an ecosystem) called number 3: Tall bushes. We were required to draw a picture of our observations about the ecosystem. We found abiotic and biotic components of the section and labelled their location and identity. After perfecting our sketches and findings, we obtained a sterile 50 mL conical tube in which we placed a sample of soil/ ground vegetation from our transect. We returned to the classroom to perform a Hay Infusion Culture. We first took 10 g of our sample and placed it into a plastic jar filled with 500 mL of deerpark water. Next we added 0.1 g of dried milk, attached the lid of the plastic jar, and mixed the contents. Finally, the jar was labelled with our group name and placed on a table without the lid.
Our transect looked as followed:
My transect was labelled It is located in the center of campus, south of the amphitheater and east of the gymnasium. The section we are observing is flat. It is centered in an arboretum. It is an flat hourglass section, surrounded by sidewalks on all sides.
The components in transect 3 were: Abiotic Components: sidewalk, lamp post, snow Biotic Components: short shrubs, trees (deciduous), leaves, soil
This lab will lead me to find out more about my transect. The Hay Infusion Culture will display the types of organisms (protists) that make up transect 3. From there, we will be able to use a dichotomous key to find out the species and their niches in the community
