Ecology correct answers "The scientific study of the relationships between organisms and their
environment".
Doubling Time correct answers John Graunt made a theoretical prediction of the growth of the
City of London, showing that the population was doubling every 64 years. He then speculated
that if the world began with one biblical date at the time of 3948 BC and started with 2 people
(Adam and Eve), and doubled every 64 years, then the world would have "far more People then
are now in it." In fact, this works out to be about 100 million people per square centimeter of
habitable land.
Population correct answers a group of (interbreeding) individuals found in the same space or area
at the same time
Demography correct answers the study of the age structure and growth rate of populations
Density correct answers the number of individuals in relation to the space or volume in which
they occur
Distribution correct answers of a population describes its geographic and ecological range,
primarily determined by suitable conditions or "habitats" for individuals of the species.
Dispersion correct answers the spacing of individuals with respect to one another
Fecundity correct answers reproductive output under ideal conditions, limited by genetics, not
the environment
Fertility correct answers the actual reproduction in a given environment. Note that it must be less
or equal to the fecundity
Immigration correct answers number of individuals that join the population per unit time
Emigration rate correct answers number of individuals that leave the population per unit time
Closed Population correct answers If there is no movement of individuals between different
populations, then the numbers of individuals are determined by local processes
Open Population correct answers if there is significant movement of individuals between
populations
Discrete growth correct answers all individuals pass through life stages at the same time, often
common with organisms affected by season
Continuous growth correct answers individuals in a population are relatively independent in
terms of when they are born, reproduce, and die. This results in overlapping generations
