We learned that in a population, you have to balance it with other populations. In this chart the shark is balenced by the minnows, the minnows are balenced by the seaweed and the seaweed is balenced eby the minnows. Right now we are making a spaceship (in floorplanner) and we are beginning to put this information into it. We are the sharks, the animals we are going to put on our ship and the seaweed are the plants that the animals eat.
