This same natural process becomes a nuisance aka body odour, when perspiration/sweat encounters bacteria on the skin. Dr Pai insists, sweat itself does not smell, but coupled with the dead skin cells, it provides a medium for the bacteria to grow. This bacteria, breaks down the sweat causing unpleasant body odour..
Abiotic Factors: : are non-living physical and chemical elements of an environment. These factors are important for the survival of the organisms of that environment. (See biotic factors. ).
Abiotic factors are parts of the environment that affect living organisms and ecosystems, while not being alive themselves, like rocks, wind, temperature, and rain. Biotic factors are living parts of the environment that affect other organisms. These include plants, animals and fungi. So biotic factors are alive, and abiotic factors are not. When looking at climate regions, you can separate their features into abiotic and biotic factors.
