Resource scarcity, such as limited food, water, and shelter, creates competition among organisms for these essential needs. When resources are scarce, individuals must compete more intensely to survive and reproduce, leading to natural selection. This competition can drive adaptations and evolutionary changes, as organisms develop traits that enhance their ability to secure resources. Ultimately, the struggle for limited resources shapes the dynamics of ecosystems and influences which species thrive or decline.
In three to five sentences explain how resource scarcity, competition, and the survival of organisms are connected.
