UL In a population, unrestricted reproductive capacity is called as a) Biotic potential b) Fertility c) Carrying capacity d) Birth rate The formula for aynonantial nonulation growth is

The unrestricted reproductive capacity of a population is called is :

Differentiate between : (i) Cannabinoids and Barbiturates (ii) Biotic potential and Carrying capacity.

How are the concepts of biotic potential , environmental resistance and carrying capacity related population growth ?

How are the concepts of biotic potential, environmental resistance and carrying capacity related to population grown.

(a) Write an equation for Verhulst Pearl logistic . Growth where N = Population density at a time t r = Intrinsic rate of natural increase K = Carrying capacity (b) Draw a graph for a population whose population density has reached the carrying capacity . (c) Why is the logistic growth model considered a more reallistic one for most animal populations ? (d) Draw a growth curve where resources are not limiting to growth of a population.

I. Population evolve to maximise their reproductive fitness, also called Darwinian fitness (higher 'r' value) in the habitat in which they live II. The population growth rate r is inversely related to generation time III. The housefly , which has a short life span and produces a large number of eggs, could be considered as a K selected species IV. under a particular set of selection pressures, organisms evolve towards the most efficient reproductive strategies V. life history traits of organisms have evolved in relation to the constrains imposed by biotic and abitioc factors in their habitat. Select the combination of correction statements

In a population showing sigmoid growth form, the population has reached its carrying capacity. What will be the value of d N/dt in this population.
