Question

Biome distribution corresponds roughly with regional variations in
(a) Climate
(b) Topography
(c) Soils
(d) All of these

Answer 1

Hint: Biome distribution depends upon various abiotic factors such as latitude, air pressure, wind, weather conditions of the area, quality of base in which the growth of vegetation takes place, etc.

Correct step by step answer:
The Biome distribution corresponds roughly with regional variations in climate, topography, and soils. Out of these climates is the most important abiotic factor that affects the distribution of biomes. Since the climate determines plant growth, it also influences the number and variety of other organisms in a terrestrial biome.
Additional Information:
- Climate change has affected the global distribution of vegetation from the distant past and will likely affect it into the future as well.
- Climate includes temperature and precipitation, and it also determines the growing season and soil quality.
- As we move away from the poles the temperature increases and as we move towards the north pole we will observe less and less vegetation in biomes.
- The biodiversity generally increases from the poles towards the equator. It is also generally greater in additional humid climates.
- Primarily biomes are determined by temperature and precipitation. Thus throughout the planet, the distribution of biome can be easily predicted
- Climate is the major factor affecting the amount and variety of plants in terrestrial biomes.
So, the correct option is 'All of these'.

Note:
- The climate is the most important abiotic factor that affects the distribution of biomes.
- The temperature increases as we move away from the pole and towards the equator.
- The amount of vegetation decreases as we move away from the equator and towards the poles.
- The biodiversity increases on moving towards the equator and away from the poles.
