Presentation transcript:

This is a fun and quick activity that demonstrates the importance of the connections among the different components (both abiotic and biotic) in an ecosystem. It also illustrates how difficult it is for humans to identify all these components and their relationships. Arrange the following events in chronological order. When you think you have the correct sequence, ask me for the answer! By the way, this is based on a real situation. Rats brought the plague. Rats increased. Cats died. Caterpillar numbers went up. WHO sent DDT to Borneo. Mosquitoes were wiped out. Caterpillars ate grass roofs. Cats were parachuted in. Cats caught lizards containing DDT. Roaches stored DDT in their bodies. Lizards disappeared. Lizards slowed down. Lizards ate roaches and got DDT.
