‘The population grows at their biotic potential for some time and the growth pattern changes because of the limiting factors’
The above statement best describes
Exponential growth
Log phase
S-shaped growth curve
Lag phase
A group of organisms of the same species that live together in a particular area is referred as
Population ecology
population
population growth
population density
A population grows exponentially when _________________
Death rates remain above birth rates
Birth rates exceed death rates
Immigration rates exceed emigration rates
Immigration rates and emigration rates are equal
The carrying capacity of a population is determined by its
Population growth rate
Death rate
Birth rate
Limiting resources
In young population , exponential growth occurs when
There is asexual reproduction only
There is sexual reproduction only
There is a discrete environmental resistance
There is a continuous supply of resources
The rate of increase or decrease of a population depends on the rate of
I natality III immigration
II mortality IV Emigration
I,II and III
I,II and IV
I,III and IV
I,II,III and IV
The maximum growth rate of a population under ideal conditions is
the carrying capacity
the environmental resistance
the biotic potential
the recruitment
Human populations on Earth are showing
exponential growth
logistic growth
lag phase of exponential growth
lag phase of logistic growth
Flood, fires, drought, storms, earthquakes, tsunami and pollutants regulate population growth
by affecting only large populations
by affecting only small populations
by affecting large populations more than small populations
irrespective of population size
If we consider a closed population with n immigration or emigration, what will happen to the population when death is more than birth?
Population shrinks
Population grows
Nothing happens to the population
Population stabilises
