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)

4)
What does the Life Table describe?
Variation of Fecundity (Fx) over a period of time.
