Activity 2

Now that you have data about at least 8 pond organisms, is time to write about what you have learned. Write a paragraph or two describing the organisms you have seen and their behaviors. Make sure that you include plants and animals and protists. How do you think these organisms might contribute to the overall activity of the pond? For example, which organisms are plants or algae (producers) and which are protists or animals (consumers)? How do you think these organisms might fit together to form an interdependent community in the pond? Draw a proposed food chain based upon the organisms you have observed or obtained information about. This information should be typed (although you may draw your proposed food chain by hand) and uploaded along with the Skill Check worksheet that you turn in.

Activity 3

The organisms that you have observed are probably only a small part of the overall pond ecosystem. It is likely that there are other larger organisms that are also part of the system. Take the information that you described in Activity 2, and speculate how it would change if you were to add the following list of organisms into the ecosystem. mosquito larvaeFrogMosquito fishGreat blue heron How would be feeding relationships change? If you were to speculate on the populations of each of the different organisms (those you have observed, and those present on the list below), which of the organisms would you expect would be present in the greatest numbers? Which would be present in the lowest numbers (think about the energy pyramid from the pre-lab)? Add a paragraph or two to the information from Activity 2 that describes these modifications and upload this is attached to the Skill Check worksheet.eck worksheet that you turn in.
