What happens to abiotic factors when biotic populations increase? Why does this take place

If biotic populations increase, abiotic factors become scarce. Like lots of the same species compete for food

Two plants growing near each other in a forest ecosystem. Explain how they would compete for several abiotic factors in order to survive

Plants competing for soil nutrients, sunlight, and water.
