Back to Board

34. Hodge Podge $500
A rabbit population’s carrying capacity is 100 rabbits. There is a drought this year. What can you call the drought? How is the population impacted by this natural occurrence?
The drought is a limiting factor on the rabbit population. The rabbit population will decrease in size because there is not enough water and the water limited the population of grass available for the rabbit to eat.
