Abiotic and biotic factors
The difference is biotic is like plants and animals (living things)but abiotic factors are non-living things.
Abiotic and biotic factors intersect because abiotic factor is sunlight and so biotic factor uses sunlight because the plants and the plants obviously need sunlight to survive.
There are 5 biotic or abiotic factors in the desert.they are heat,water,soil,plants,and oxygen levels.
If all thos biotic/abiotic factors didn't exist in the desert,then there probably wouldn't be a desert.it would be like a dead city.
