Question

Biotic factors are :

• A. Atmospheric factors which influence life
• B. Chemical factors of soil which effect life
• C. Physical factors of soil which effect life
• D. All living organisms which influence other organisms

Answer 1

The correct option is D All living organisms which influence other organisms

Biotic and abiotic are the two essential factors responsible for shaping the ecosystem. The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.) and chemical agents (different gases and mineral nutrients present in the air, water, soil, etc.) in an ecosystem. Therefore, both the abiotic and biotic resources affect survival and reproduction process.

Living organisms have effect on other living organisms and these constitute biotic factors or living factors. A biotic factor is a living organism that shapes its environment. Biotic and abiotic factors work together to create a unique ecosystem.
