Growth in agar dishes
Air dish
The microbes take different shapes depending on the kind of plate used. The numbers of colonies were less compared to that of water and soil. Ideally, the exposure time and disturbance played a role. The formation of fungi and bacteria depicted different shapes. They are the group in the cluster and have greenish matter. Some take the form of a tennis ball or starfish.
Soil dish
The exhibition of microbes in a soil dish indicated evidence of staining (Invitrogen) dye. The radius of the microbes was at 0.24mm. The colony showed a corresponding growth when exposed to the soil. Further, testing showed phenotypic diversity (Microbes: Earth's First Inhabitants, n.d, p.169). The shapes often differ depending on the host. The microbes have greenish color while others have a variety of colors that enhance their adaptation.
Water dish
The defining characteristics indicate the presence of fecal bacteria. Notably, microbiological indicators show that the use of water that is contaminated may lead to illness. The water dish showed the colonies of bacteria manifesting in water that lead to waterborne diseases. They have several shapes, spherical, corkscrew and vibrio, a shape like a comma.

Microbes have similarities and differences in the way they manifested themselves in hosts. Depending on the environment most of the microbes exhibit similar characteristics. They are attached to their host. In all the cases observed, in soil, air and water. Soil and water microbes colonies were more compared to the air microbes. The microbes inhibit the functionality of the host. In essence, therefore, they disturb the normal functioning of the host. The infections have the human being as their primary host. They form a basic natural reservoir for the infectious intermediaries. On the other hand, they differ in the makeup (Microbes: Earth's First Inhabitants, n.d, p.170). Extreme temperatures affect them. The microbes that survive in the air cannot survive in water. The bacteria and viruses have a different makeup. The bacteria lack chlorophyll. Further, they have exhibit-varying temperatures that support their survival. Bacteria in humans often survive at 37 degrees census while some bacteria survive in cold temperatures.
The microbes are tiny hence hard to see them with a naked eye. They can be transmitted through, air, soil and water. They are often referred as “germs”. Further, they belong to four groups that enhance their manifestation. The groups include protozoa or fungi, bacteria, and viruses.

The organism in the natural environment can change to be agents in the spread of disease. Often it occurs due to certain favorable conditions that Further, Global-warming increase the transmission of disease. The temperatures for the existence of the microbes tend to be ideal when global warming is experienced. The zoonotic disease is predominantly evident in infecting hosts that are non-human. Ideally, the transmission could be direct or indirect, for example, physical contact aid in the transmission of diseases from uninfected host to a healthy one. The shapes of the microbes help them in surviving the varying temperatures (Microbes: Earth's First Inhabitants, n.d, p.173). Further, the shapes and size aid them in hiding in the host's body hence its habitat does not interfere. The scientific analysis indicates that the microbes have characteristics that enhance the spread of disease. The diseases include coronary artery, specific kinds of cancer, multiple sclerosis, diabetes and chronic lung infections.
Ideally, most microbes do not use oxygen to survive. However, the microbes that do not rely on oxygen may utilize nitrogen in generating energy for their survival.
