Lab Section 66 6 March 2008 Materials and Methods Ecobeaker is a simulation or artificial ecosystem program set up through the use of computer technology that teaches ecology, conservation biology, and evolutionary biology. This program, Ecobeaker, is used by students and professionals of the biology field because it allows researchers access to a lifelike ecosystem right in the classroom with no traveling or expenses required in comparison to studying a natural ecosystem further away at less convenience. When studying or using the Ecobeaker program individuals can observe and collect data such as what organisms are consuming, how fast their population is reproducing, and the effects of predator-prey relationships throughout several simulations in the constructed ecosystem. For example, in the first simulation conducted of the Ecobeaker program a study of an 800 day period of an ecosystem containing Green Algae (Chlorophyta), Blue-Green Algae (Cyanophyta), Bosmina, and

Unformatted text preview: Daphnia were observed. Also, stopping the program at an interval of every 200 days provided information and data on what levels of organism activity were occurring in this lake environment. Furthermore, in the second simulation, in addition to the previously four mentioned organisms, minnows were added to the lake. An observation of algae and animal population levels occurred during time intervals ranging from 400, 600, and 800 days were noted after the secondary consumer, minnows, was added to the ecosystem. In conclusion, in the third and final simulation there was an addition of a tertiary consumer, trout, to the Chlorophyta, Cyanophyta, Bosmina, Daphnia, and minnows that were already present in a large lake ecosystem. During this final simulation or experimentation once again scientific data, algae and animal populations, was collected at 400, 600, and finally 800 day intervals....
