Today in science we made a big food web of the population of the great lakes. I had two animals, one of which was a Lake Whitefish and the other was the Great Blue Heron. The Great Blue Heron was at the top of the food web while the Lake whitefish was toward the middle. We got strings to show the food chains. In the end, I had so many strings because the Great Blue Heron ate so many organisms in the food web. I wonder what would happen if a disease came and wiped out two of the Great Blue Heron’s prey’s population. This activity helped me understand direct and indirect interactions because when we took out a population the chain would fall, and anyone who was connected to that chain would have a piece of string that would fall.
