exponential growth formula,exponential growth definition,exponential growth curve,logistic growth,logistic growth definition

Exponential growth and logistic population growth are the example of population growth. And the definition of population growth is ‘population growth varies from region to region. This number increases if there are living things or individuals in a population.

 

EXPONENTIAL GROWTH	LOGISTIC POPULATION GROWTH
1.      I exponential growth the population grows exponentially, hen resources are unlimited or plenteous	1)      In logistic population growth, if there are limited resources, the growth is logistic. As logistic grow , population expansion slows as resources dwindle
2. In exponential population growth the growth is unrestricted.	2)      In logistic population growth the growth is restricted due to resistance in environment.
3.They depends basically on the size of the population	3)      They depend on the size of the population, competition and amount of resources.
4. formula for exponential growth is dN/dt=rN        N=Population size , r = intrinsic rate of       natural increase in population	4)      Formula of logistic growth is dn/dT=Rn(K-N)/K
1.      5. Exponential growth does not have the carrying capacity.	5)      Logistic population growth has carrying capacity.
1)      6. Its increase along with increase in the    size of the population.	6)      In which the growth rate decreases and the population size increases.
7. Environmental factors climate, food, space also effect on it.	7)      Environmental factors have major effect on its growth
8.      In exponential population growth population crash occurs due to mass mortality.	8)      In which population crash occurs very rarely
9.      In exponential population growth there are two phase                                 I.            Leg phase                               II.            Log phase	9)        In logistic population growth there are four phases Declaration phase and the stationary phase are found
10.    Shaped curve is formed by the exponential population growth. This curve called exponential curve	10)  S-shaped curve are found by logistic population growth. This curve is called logistic curve.
