Resource scarcity occurs when there are limited resources available in a particular environment. This leads to competition between organisms for those resources, such as food, water, and shelter. The organisms that are better adapted and able to secure these resources have a higher chance of survival and passing on their genes to the next generation. Therefore, the competition for scarce resources plays a critical role in the survival and evolution of organisms in a given ecosystem. make this like a 7th grader wrote it

When there's not enough stuff like food, water, and places to live in a certain place, it's called resource scarcity. Because there's not enough to go around, living things have to fight each other for those things. The ones that are better at getting what they need have a better chance of staying alive and having babies. That's why competition for limited resources is really important for living things to survive and change over time in a certain area.
