Whereas Afghanistan has a huge proportion the its populace in child-baring or soon to be child-baring period categories and will likely see rapid population growth uneven war and famine reason the death rate to match the birth rate. P. 1189,
Which form of dispersion sample is shown below and also which factors may account because that this type of dispersion?, Clumped dispersion. Communal living explains clumped dispersion in wolf populations. Other varieties of organisms might be clumped in certain microhabitats, such together fungi.

Which type of life history reproductive strategy (semelparity or iteroparity) would be favored in very variable, unpredictable environments?Semelparity (In unpredictable environments, the odds that the offspring live, or even that the parent resides long enough to reproduce an ext than once, are lower, therefore it makes evolutionary sense to blee as many offspring as feasible in the "one-shot" pattern of big-bang reproduction that is recognized as semelparity) p. 1180
Which kind of life background reproductive strategy (semelparity or iteroparity) would certainly be favored in stable, predictable environments?Iteroparity (In predictable environments, parental are more likely to have the ability to survive and also reproduce again, however competition for resources is fierce since the populace is most likely to be close to transporting capacity. Therefore, that is a better strategy to have fewer offspring and put an ext energy into taking care of them, or making fewer but larger eggs with much more nutrients therefore the offspring are bigger and better able to take treatment of us at birth) p. 1180
