What is your hypothesis for this experiment? A. Pillbugs will move away from the choice chamber containing cornstarch, because they are repelled by cornstarch B. Pillbugs will move toward the choice chamber containing cornstarch, because they are attracted to cornstarch C. Pillbugs will have random movements between chambers, because they are indifferent to cornstarch What is your strategy? A. I will add 10 pillbugs and then continue to add pillbugs so that the number of pillbugs in each container remains equal. B. I will put one pillbug into the choice chamber and see where it immediately goes. C. I will add 5 pillbugs on the left and 5 pillbugs on the right and count the number of pillbugs on each side at regular intervals of time. What is your experimental setup for the top choice chamber?

Ecological Interactions

The study of the ecological interactions between living beings and their physical environment, including humans, is ecology. It aims to understand the crucial links between plants and animals and the world around them. Ecology also gives knowledge on the advantages of ecosystems and how we may use Earth resources to ensure that future generations have a healthy environment.
