OR


Every year in winter Siberian cranes migrate from Russia to India forbreeding. In the year 2006, a survey was done which has the values in the given equation


N(t+1) = Nt+ {(B+I)–(D+E)} as follows


N(t+1) = 1200 + {(600+700)–(200+800)}


On the basis of above answer the followings


a. Natality rate


b. Mortality rate


c. Number of cranes immigrated


d. Number of cranes emigrated


e. Population of cranes in India in year 2006.



a. Tropical Rain forest


b. Grasslands


c. 00-100C


d. 50-200cm


e. Arctic and Alpine Tundra


OR


a. Natality rate= [600/1200]*100


=50%


b.Mortality rate= [200/1200]*100


=16.7%


c. No. Of cranes immigrated= 700


d. No. Crane emigrated=800


e. Population of crane=1500
