How do the biotic and abiotic limiting factors of an ecosystem determine its carrying capacity?

Biotic factors are living things in the ecosystem.
abiotic factors are nonliving things in an ecosystem.
If there is not enough biotic factors in an eco system there will not be enough food such as plants and animals.
And if there is not enough abiotic factors there will be no places for shelter and water.
The ecosystems abiotic and biotic factors make a set carrying capacity for an ecosystem,because if there are not enough biotic factors there would be no food and if there is not enough abiotic factors then there would not be enough shelter or water to live.
hope this helps
