Resource scarcity leads to competition among organisms for limited resources such as food, water, and shelter. This competition is a driving force in natural selection, where only the organisms best adapted to obtain and utilize these scarce resources survive and reproduce. Organisms that are able to outcompete others for resources are more likely to survive and pass on their advantageous traits to future generations. Ultimately, resource scarcity and competition play a crucial role in determining which organisms are able to thrive and survive in their environment.

When there isn't enough of something that living things need, like food or water, they have to compete with each other to get what they need to stay alive. The ones that are better at getting what they need have a better chance of surviving and having babies that are also good at getting what they need. So, having to compete for resources helps some animals and plants be stronger and better suited to survive in their environment.
