**[Experiment Questions]** 1. Name three pieces of equipment used to catch animals in a grassland habitat. Pooter, sweep-net, Tullgren funnel.  1. Name two sources of error in experiments. Misidentification, miscounting 1. How would one measure light intensity in a habitat? By using a light intensity metre. 1. How would one measure soil pH in a habitat? By use of a pH meter. 1. How did you reduce bias in your experimentation? I stood with my back to the grassland habitat and threw a pen over my shoulder. I then recorded the number of the organisms present there. 1. How did you mark the animals captured in the ecosystem? In a way that would not harm them or make them more visible to their predators.  1. Name one way of displaying your results. In a bar chart. 1. How would you identify an unknown animal? By use of an identification key.  Q. Design a food chain based on your field study: Q. Design a food web based on your field study:  Q.
