Explain the concept of supply and demand, but pretend you are a whale. use examples a whale would use
Supply is just like how much krill there is in the ocean. If you come across a plentiful patch of krill, all whales are happy and fed. But if krill becomes scarce, the whales become less happy.
Demand is like being hungry. It takes a lot of krill to feed us whales, so we are constantly seeking out more to eat. The more hungry whales there are, the higher the demand is.
