Drastic short term reductions of population size will affect the species symbiotically related. The reduced population's food source will increase, due to decreased consumption; that which feeds off the now reduced population will decrease in numbers due to dying or to migration to better food. Populations which rely on the population in question for protection will also be negatively affected. Animals will leave less waste, which is less energy available to continue the life cycle. Tall trees would no longer offer a canape of shade, nor a means to prevent moisture loss. If the population decrease is short-term, the return to old populations will require a readjustment, as other life forms will have seized the new ecological space allowed to make for new niches. A different environment with the same needs and its increased competition will provide the struggle through which the new most fit are to survive.
