Answer:
The increase of soil temperature have resulted in decreasing the diversity, body mass, number and size aspects of flora and fauna of soil.
Explanation:
Soil fauna includes protozoa, ascarides and nematodes. Soil flora comprises of bacteria, algae and fungus. The soil flora and fauna plays a vital role in breaking down, decomposition and nutrient absorption to the soil making it more viable for cultivation of plants. They too affects the structure and nature of soil. This flora and fauna forms the biomass and subsequently the humus of the soil. The increasing temperature of soil, render it hostile for soil flora and fauna to thrive, hence it results in decrease of biomass and diversity of those organisms.
