What type of head and jaw does the Salmon and Steelhead trout have. Say that we are comparing the annual growth rates of two countries GDP. Large fractions of individuals past reproductive age mean a population is likely to shrink. The population pyramid is smaller at its base, meaning that there are fewer young individuals: fewer people who are able to reproduce. I am talking about the bounces in the last graph. And the results can be dramatic: after 1 1 day ( 24 24 cycles of division), our bacterial population would have grown from 1000 1000 to over 16 16 billion!
