    • For example, when you arrive at grass hopper, it is connected to rat and frog, so that player should have 2 yellow rolls. Similarly, fruit-fly should have 3 rolls and the same continues for the other organisms and a food web is slowly formed!

    • Add a new animal to the final food web to explore changes in nature

    • Remove some animals in the final food web, simulating extinction, and see the gradual collapse of the food web

    • Yarn should be held tight and firmly by each participant
