Question No : 3
When food
and space for a population are unlimited?I. Each
species has the ability to realize fully its inherited potential to growII. Then
it is equal to  III. It
is described by J-shaped curveIV. It is
described by S-shaped curveV. Than
it has greater intrinsic rate for resourcesVI. There
are more competition among themselfChoose
the incorrect statements |
| a) | I, II and III | b) | II, IIII and IV |
| c) | IV and VI | d) | IV, V and VI |
Answer No : 3
(c)When
food and space are unlimited than population.(i)
Increased by using its maximum biotic potential(ii)
Shows exponential growth (iii)
Shows exponential growth curve also called J-shaped curve(iv)
Show greater intrinsic rateA
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 3rd phase in which the
population reached the carrying capacity level and population get stationary
position. No of death = No of death |
