ELI5: Explain Like I'm 5

Carrying capacity

Carrying capacity is the maximum number of living things that can live in an environment and still have enough food, water, and space. It is like when you have a birthday party at your house. You can have a certain number of friends over that can fit in your house and have enough food and drinks and space to have fun. If you have too many friends the house gets too crowded and it is not fun anymore. The same happens with carrying capacity and the environment!
