In a 50 km² grassland, Population A has 10,000 rabbits, and Population B has 25,000 rabbits in a 30 km² forest. The sustainable population density for both habitats is between 150 and 300 rabbits per km².
Question: Calculate the population densities of Population A and Population B. Which population density is unsustainable?
Population A = 10,000rabbits / 50km2 = 200 rpkm2
Population B = 25,000rabbits / 30km2 = 833 rpkm2
Population B is unsustainable.500
