Succession, the process of a community changing over time, can be broken down into sub groups such as ecological, primary, pond, and secondary. Ecological succession being the most basic. In the Succession Lab, we observed a community in a ecosystem. As we recorded the data each class, we observed that succession takes place with rapid speed for in each observation, a new specimen is identified.
A niche is how the organisms live, what their role in the community is. For example, an ecological niche is how a certain organism reacts to limited resources and competitors. Another definition for a niche is the role that an organism plays in a food chain. When the resources are abundant, less competition in the community, or even when their predators are scarce, they grow in size because their living conditions improve. For example, a niche of a bacteria is a decomposer. In the lab, the level of population increased in a short period of time. In the second day the population of paramecium was 800. On the third day the population increased to approximately 2,000. As paramecium are increasing, the cynobacteria are decreasing. They are the food source for the paramecium. On a single slide, we observed at least one or two cynobacteria. These organisms were observed within the first hour of the experiment therefore making it very difficult to identify organisms.
On the second day, there was not much difference seen with the naked eye. But when a slide was created, we identified very small bacteria with limited movements and medium sized protists with lots of movement. After 48 hours, it can be concluded that the level of diversity increases as new specimens take part in the food chain. A chain of cynobactera was also seen under the microscope. After 96 hours on the third day, there was an increased population of bacteria, protist, and paramecium. The bacteria found were easier to identify than previous observations and the protists were more active.
