Detailed explanation-1: -The correct answer is Air, water, heat, and light.
Detailed explanation-2: -Abiotic factors such as drought, light, salinity, seed burial depth, soil pH, and temperature as well as disturbance events such as a fire, flooding or tillage can play an important role in initiating or inhibiting seed germination [3–4].
Detailed explanation-3: -Abiotic factors include water, sunlight, oxygen, soil and temperature. Water (H2O) is a very important abiotic factor – it is often said that “water is life.” All living organisms need water. Plants must have water to grow. Even plants that live in the desert need a little bit of water to grow.
Detailed explanation-4: -Like water, oxygen (O2) is another important abiotic factor for most living organisms. Oxygen is used by cells as an energy source.
Detailed explanation-5: -Environmental factors such as temperature, light, pH, and soil moisture are known to affect seed germination (Chachalis and Reddy 2000; Taylorson 1987). Burial depth of seed also affects seed germination and seedling emer-gence.
