Populations are influenced by fluctuations in any of the abiotic cycles. The fluctuations of seasonal cycles can cause populations to hibernate, migrate, or breed. Organisms breed as a result of seasonal fluctucations that cause them to have a limited resource supply. Fluctuations in the phosphorus cycle can cause <span>changes to aquatic ecosystems, either positive or negative.</span>
