Dear student,        
Please find below the solution to the asked query                                                                

18. b. The small number of tigers that are surviving is a cause of worry because if they are all dead, then their genes will be lost for permanently. Their genes will be not passed on to other generations and we will not be able to see any tigers in future. Small number of tigers means less chances of variation. The variations are important in maintaining the stability of a species by natural selection.
