Invasive species are typically introduced into ecosystems by humans.
Observe the food web below. Use the space below to form three predictions on what would happen if the everglades crayfish was removed from the web.

This question has more than one correct answer. Be sure to comment on how it may affect other trophic levels. What the organism consumes, and what consumes that organism. If the organism is predated on, what effect would it have on the predator? Would the predator have to prey on another organism? Will it affect the population of the “other” organisms?
