Question

LIST AT LEAST THREE EXAMPLES OF HOW MICROBIAL PHOTOTROPHS ARE IMPORTANT CLINICALLY AND ENVIRONMENTALLY

Answer 1

Microbial phototrophs are organisms like algae and cyanobacteria which carry out their cellular metabolic processes by using the energy from light.

These are important environmentally as they are present on the surfaces exposed to light in terrestrial as well as aquatic environments. Here, algae and cyanobacteria are the major primary producers of energy as they generate energy and reduce carbon dioxide. This helps to provide the environment with organic substances and oxygen.

Clinically the cyanobacteria has contributed to many aspects of human life like it is used for several medical purposes. Many Proterozoic oil deposits are attributed to the activity of cyanobacteria.

Answer 2

Cyanobacteria are primitive organisms where chloroplasts are believed to be originated. These phototrophic organisms benefit the environmental and the clinical aspects because of their unique physiology. For instance, they contribute to energy attainment from sunlight which helps other organisms gain energy when this is consumed. Another is the contribution to biogeochemical cycles. And lastly, how these can aid in many medical discoveries and treatments.
