It literally means âby way of e-mailâ which probably doesnât help either. In the âold days,â paper letters could be sent via courier, via air mail. It simply means e-mail was involved.
Taxonomy. Bacteria are members of the prokaryote group. In contrast to eukaryote cells, bacteria lack a cell nucleus and customarily have no organelles. The bacteria domain can be grouped into two major categories: (a) Eubacteria and (b) Cyanobacteria.here are approximately 50 million bacterial organisms in a single gram of typical surface soil. The worldwide bacterial biomass exceeds that of all plants and animals on Earth. However, the majority of bacteria have not yet been characterised.
Decay. E. coli bacteria (Photo from Rocky Mountain Laboratories, NIAID, NIH). Decay is essential to our survival â it helps to digest food, and to recycle materials in our environment. Sometimes it can cause problems too, such as food spoilage (food going off).The main groups of decomposer organisms are bacteria and fungi.Bacteria are single-celled microscopic organisms. Fungi are often larger organisms that include moulds and mushrooms. They both cause decay by releasing enzymes which break down compounds in their food so it can be absorbed by their cells.ometimes it can cause problems too, such as food spoilage (food going off).
