Explanation

A population growing in a habitat with limited resources shows three phases. (i) Lag phase It is the initial phase in which a population adapt themself according to the environment and starts to increase their number (ii) Log phase It is the second phase in which a population use its resources maximally and increases their number exponentially. Number of birth >> Number of death (iii) Stationary phase It is the 3^(rd) phase in which the population reached the carrying capacity level and population get stationary position. No of death = No of death [image:13_image36.emf]
