WebThe life history of a species is the pattern of survival and reproduction events typical for a member of the species (essentially, its lifecycle). Life history patterns evolve by natural selection, and they represent an "optimization" of tradeoffs between growth, survival, and reproduction. One tradeoff is between number of offspring produced ... WebAgave and Century Plants - the same thing? Agave is a genus with many species. They're called century plants because they grow for many years, flower once, and then die. This is a reproductive strategy for harsh environments called monocarpy or semelparity. It costs a lot for them to reproduce because they are bat pollinated.
