Q Getting Started Ecosystems have an extremely complex web of cause and effect. Changing one connection or altering the population of any species within an ecosystem can have impactful, cascading effects on all other species within that ecosystem. In this lab you will have the opportunity to create an ecosystem, make predictions regarding species success, and observe, through simulations, how species will interact over time. Upon successful completion of this assignment, you will be able to: • Make scientific predictions, analyze scientific data and theorize how the information can be applied. ________________________________________ Resources • Textbook: Essential Environment: The Science Behind the Stories • Website: The Habitable Planet: A Systems Approach to Environmental Science, Interactive Labs • File: WS2 Lab Ecology • Video: WS2 Lab Tutorial. ________________________________________ Instructions 1. Review the rubric to make sure you understand the criteria for earning your grade. 2. Read Chapter 4 in Essential Environment: The Science Behind the Stories 3. Watch WS2 Lab Tutorial. 4. Download the WS2 Lab_Ecology file. 5. Navigate to The Habitable Planet, Ecology Lab a. Read and complete the lab lessons The Producers and Food Web b. Record data and answer questions in the WS2 Lab_Ecology document (do not download the data table from the interactive lab) 6. The writing must follow APA requirements. 7. When you have completed your assignment, save a copy of your completed lab document for yourself and submit a copy to your instructor using the Assignment submission page by the end of the workshop. ________________________________________ Access the associated rubric Access the Assignment submission page Navigate to the website https://www.learner.org/courses/envsci/interactives/ecology/. Complete the lab lessons entitled “The Producers” and “Food Web”. Record your predictions and data in the tables below and answer the analysis questions that follow each step.

1. What assumptions does this model make about co-dominance as well as the general terrain of the ecosystem? This dominant plant and invasive plant that clearly did not survive. The general terrain of the ecosystem does not support both of these plants and the only one can have habit there. 2. Do you find one producer to be dominant? Why might one producer be dominant over another? Plant A is the dominant producer because the terrain supports and rotted it to multiple. Herbivores would be interested in plant A over plant B. Dominant producers tend to take over a terrain and rapidly grow more than other and probably stunt. Plant B terrain has crumbled and eventually dies out.
