No, biotic and abiotic factors are the environmental conditions that the organisms have to face to live in a specified environment. Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH.Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition... The development of organims is under the control of abiotic factors.

The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controling the biotic factors of an environment.
