Today in class we introduced the vocabulary term Troph-. This term means "to nourish." In the context of ecology we see what is the flow of nourishment from organism to organism. In the Ecobeaker modeling program the organisms we are dealing with are algae, zooplankton, trout and pike. Students will work with the program to see what happens in terms of an organisms population when one of the organisms is removed or introduced back into the food chain.
When students have completed the modeling activity they will answer the following journal questions on their Google document.
Lake Invaders: Exercise #2 - Go Fish Follow-up
1.
How is the Lake Invaders computer model different from the food
chain/web we have seen or drawn in the past? How are they similar?
2. Describe what happened to the lake ecosystem when the trout (top predator) was removed?
3. What do you think might happen to the populations of other species when we add pike to the lake ecosystem?
