Which of the following is most important parameterm chosen for assessing impacts of any biotic or abiotic factor on population growth?

Given below are four jumbled sentences. Select the option that gives their correct order A. However, the rate of population increase is another important factor to consider. B. This change can be expressed in two ways. C. Growth of population refers to the change in the number of inhabitants of a country. D. First, in terms of absolute numbers and second, in terms of percentage change.

(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.
