the two climatic factors which largely determines the vegetation n soil type

1. temperature & precipitation
2. temperature and light
3. light and precipitation
4. light and weather

The correct option is 1.
The biodiversity characteristic of each extinction, especially the diversity of fauna and subdominant plant forms, is a function of abiotic factors and the biomass productivity of the dominant vegetation. In terrestrial biomes, species diversity tends to correlate positively with net primary productivity, moisture availability, and temperature.
