It takes all types to populate a community. Coexistence is easier for plants than animals. Nobody is called Jones to be kept up with! Everyone can flourish when there is abundance.
Everyone uses natural a particular endowment in facing hardship; capitalises on the features delivered by the genes when they are favoured by conditions, suffer when they are not.
Like storing water and food in leaf, stem, root or bulb for later. And having a feast and a flourish in peak times, each according to it's nature. All in aid of producing healthy children who can perform later.
