In three to five sentences explain how resource scarcity, competition, and the survival of organisms are connected?

Write like a 7th grader would

Resource scarcity, competition, and survival of organisms are all connected because when there isn’t enough food, water, or shelter for everyone, organisms have to compete with each other to get what they need to survive. This competition can be tough because not everyone will be able to get what they need, meaning some organisms might not make it. Those who are better at competing for resources will be more likely to survive and pass on their genes to the next generation. This shows that in nature, the organisms that are best at taking care of themselves are the ones that are most likely to stick around.
