The Food Chain Gizmo shows a food chain with hawks, snakes, rabbits, and grass. In this
simulation, the hawks eat snakes, the snakes eat rabbits, and the rabbits eat grass.

aC s

2. Select the BAR CHART tab, and click Play ( ). What do you
notice about each population as time goes by?
is
The snake population increased a little bit. The grass grew a lot, and the hawk population
Th
did not grow . And the rabbit population increased by 1.
_________________________________________________________________________
If populations don’t change very much over time, the ecosystem is in equilibrium.

3. Notice the populations decrease as you go from the bottom of the food chain to the top. Why
do you think this is so? The population of food will increase as the food chain goes up, but
food has to be available for the lower levels of the food chain.
