B. They compare traits that species have
I’m pretty Sure it’s A sorry if i’m wrong
Population density =number of individual divided land area
land area should be in square kilometers
therefore 120 ha =120 x0.01=1.2 square kilometer since 1 ha=0.01 kilometer square
total population= (80 x 1500)/100=1200
population density is therefore=1200/1.2=1000
