- Write a conclusion that includes an analysis of various limiting factors and how they impacted population growth. State the purpose of the experiment using the question. Explain the background of the experiment and briefly describe the procedure. When explaining the background of the experiment, you are giving a overview of limiting factors. You should include information found in the background of the lab. Include a summary of the steps used to gather data. Describe how each of the limiting factors you studied in the simulation affected population growth and carrying capacity( migration, predation, food, disease, and pollution) include a reason why you think the limiting factor affected the population growth in this way.arrow_forwardWhich of the following accurately describes a trophic cascade? a.
