Sunlight, water, temperature and soil type are the abiotic factors that help to characterize a biome.
Step-by-step explanation:
Abiotic factors are nonliving characteristics of the environment. Biome is characterized based on the abiotic factors like availability of sunlight, water, and temperature and soil type.
Biome occupies major area on Earth. They have different climate and different living beings. Some of the biomes are
i) Tundra
ii) Tropical Rainforest
iii) Temperate Forest
iv) Grasslands
v) Deserts
The plants and animals of each biome have their own characteristics to persist in their biome. The condition of the soil determines the living factor of the biome.
