.
.
 1) The Leslie Matrix is used in ecology to model the __________. changes in a population of organisms over a period of time. changes in only age group of organisms over a period of time. changes in only fecundity of organisms over a period of time. None of the above.

 2) The value of first row in the Leslie matrix is represented as ____ and The diagonal values starting from second row in the Leslie matrix is represented as _____ . Age classes (x) and Population vector (n) Fraction of individuals that survives from age class x to age class x+1 (sx) and Fecundity (Fx) Population vector (n) and Age classes (x) Average female offspring per female of the population (mx) and Population vector (n)

 3) Leslie matrix is _________ model of population growth. Discrete Continuous Discontinuous All of the above

 4) What does the Life Table describe? Variation of Fecundity (Fx) over a period of time. Variation of age class over a period of time. Variation of birth rate over a period of time. How mortality varies with age over a time period.

 5) 4) Let the total number of individual in the population is = 112 , and the population vector =[20,10,40,30] , Find the Finite rate of change (λ)? 1.02 1.12 1.16 1.0

 6) The sigmoid growth curve is characteristic of most survivorship curves. True False
