Space is a limiting factor for a population because when the population starts growing then there won't be enough space for all the organisms so then some of the organisms have to leave that area and find a new habitat.
That all organisms are variations. That there are many more organisms born than can be supported by the available resources. That their is a struggle for existence and some organisms will be better adapted to survive and out reproduce their fellow organisms. That these organisms that do this will leave descendents that have these same characteristics which will change the morphology and behavior in these population of these organisms over time.
By adapting themselves or being excepted into that specific population. Establishing a sense of belonging. Then, only leaving when the organisms adaptation is impossible or they have deceased from population.
they change size when animals come bypass the area and practically leave seeds on the ground so the plants can grow then when more and more plants grow small organisms at first start coming but then bigger organisms come and keep coming...so thats how a population size change
There is no gene flow - APEX
individuals leave a population when you know how people joing certain states that's creating more population but when people leave a population it becomes a lower population

Think of coevolution as an arms race. The rabbit population develops faster running ability and the fox population must have variant individuals that can keep up and these individuals are the ones who will be reproductively successful and leave these traits to the next generation of foxes and the alleles in the fox population change in frequency. Meanwhile the slower rabbits are eliminated from the population and the faster rabbits are reproductively successful, and so on. Only the limitations of physics and the realities of variant organisms keep this arms race within the confines of the physical and biological world.
