species being affected by the loss of an apex predator‚ and the way in which they are affected‚ is not always fixed. In a study conducted by Pujoni et al. (2016)‚ they observed the effect of adding an intermediate predator to a classic tri-trophic system. The original three-level chain under observation was: planktivorous fish- caldocera (water flea)- algae. They noticed that the addition of a predator reversed the correlation between the apex predator (planktivorous fish) and the lowest trophic level

In this lab‚ we are trying to see which prey (beans) would survive and which predators (students with different type of mouthpart) would survive. I think green bean would survive because it is very tiny. The predator use hand as mouthpart would survive. To start the lab‚ we need seven different beans together‚ which includes split pea‚ kidney bean‚ large white bean‚ black bean‚ pinto bean‚ small
