Resource scarcity means that there aren't enough things like food, water, and shelter for all living organisms. When resources are limited, different species and individuals compete with each other to get what they need to survive. This competition can lead to stronger or better-adapted organisms surviving and thriving, while those that can't compete may struggle or die out. In this way, resource scarcity affects how organisms live and evolve over time.
In three to five sentences explain how resource scarcity, competition, and the survival of organisms are connected.
