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.
Bacteria and other microbes play the important role in environment of DECOMPOSERS, which act in the last stage of food chain. These microorganisms like bacteria cause the brea â¦ kdown of energy rich organic compounds.xample: Nitrobacter. 3. Bacteria that denitrifies nitrates (NO3-) in the soil (called denitrifying bacteria). Example: Pseudomonas denitrificans. 4. Bacteria that fixes nitrogen (called nitrogen-fixing bacteria). Examples: Rhizobium (which is symbiotic) and Azotobacter (which is free-living). 5.
