Definition - What does Tensile Strength mean? Tensile strength is the ability of a material to withstand a pulling (tensile) force. It is customarily measured in units of force per cross-sectional area. This is an important concept in engineering, especially in the fields of material science, mechanical engineering and structural engineering.
Microorganisms In A Compost Pile. Microorganisms such as bacteria, fungi, and actinomycetes account for most of the decomposition that takes place in a pile. They are considered chemical decomposers, because they change the chemistry of organic wastes.
This soil food web is the basis of healthy, living soil. Significant soil organisms involved in the soil food web include: 1) bacteria, 2) fungi, 3) protozoa, 4) nematodes, 5) arthropods, and 6) earthworms. 1  Bacteria â Bacteria are simple, single-celled microorganisms.2  Bacteria inhabit a wide variety of habitats, including soil. The bacteria contain more nitrogen than the protozoa can utilize and some ammonium (NH4) is released to plants. 2  Protozoa also prevent some pathogens from establishing on plants and function as a food source for nematodes in the soil food web. 3  Nematodes â Nematodes are small, unsegmented round worms.
