How does competition affect population growth?

Purpose
In this investigation you will conduct an experiment and grow two species of the protozoan Paramecium, alone and together.  You will then compare growth curves of the populations of each species.

Objectives:

• Demonstrate how competition for natural resources in the environment can affect population growth.
• Explain how availability of resources, such as food, can be limiting for populations.

Assignment
Go through the virtual lab.  Create a doc, slideshow, spreadsheet, etc for this assignment.  You need to have screen shots for each part explaining what is happening in each shot, a data table with information from the experiment.  Also answer the analysis questions from the journal.
At the end of your doc, you need to write a conclusion paragraph following the claim, evidence, reasoning format.
