By playing shark tank, we learned about the food chain. We didn’t know this while we were playing, but the sharks, minnows, and seaweed represented something. The sharks represented us, the people. We are at the top of the food chain. The minnows represented the animals that we eat. They are in the middle of the food chain. And the seaweed represented the food that the animals eat. They are at the bottom of the food chain.
