Soil mesofauna do not have the ability to reshape the soil and, therefore, are forced to use the existing pore space in soil, cavities, or channels for locomotion. Soil Macrofauna, earthworms, termites, ants, and some insect larvae, can make the pore spaces and hence can change the soil porosity, [5] one aspect of soil morphology. Mesofauna ...
Soil life, soil biota, soil fauna, or edaphon is a collective term that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface. These organisms include earthworms, nematodes, protozoa, fungi, bacteria, different arthropods, as well as some reptiles (such as snakes ...
Fungi are abundant in soil, but bacteria are more abundant. Fungi are important in the soil as food sources for other, larger organisms, pathogens, beneficial symbiotic relationships with plants or other organisms and soil health. Fungi can be split into species based primarily on the size, shape and color of their reproductive spores, which ...
The weight of casts produced may be greater than 4.5 kg per worm per year. By burrowing, the earthworm improves soil porosity, creating channels that enhance the processes of aeration and drainage. [17] Other important soil organisms include nematodes, mycorrhiza and bacteria. A quarter of all the animal species live underground.
The Actinomycetota genus Bifidobacterium is the most common bacteria in the microbiome of human infants. [11] Although adults have fewer bifidobacteria, intestinal bifidobacteria help maintain the mucosal barrier and reduce lipopolysaccharide in the intestine.

[10] [11] Soil temperature influences biological and biochemical processes in soil, playing an important role in microbial and enzymatic activities, mineralization and organic matter decomposition. [12] Air is vital for respiration in soil organisms and in plant growth. [13] Both wind and atmospheric pressure play critical roles in soil ...
