Question No : 9
               The growth rate of a population stabilizes after     

                a)          Logarithmic phase          b)          Stationary phase     

                c)          Carrying capacity          d)          Negative acceleration phase     

Answer No : 9
     (c)Carrying capacity can be defined as the level beyond, which no major increase can occur. This limit is constant and represented by K. When a population reaches the carrying capacity of its environment, the population has zero growth rate so, the growing rate of a population stabilizes around the carrying capacity.
