a) Single cell protein(SCP)
Single cell protein is a protein obtained from pure or mixed cultures of algae, bacteria etc. that have 30-70% of protein content in their dry mass. Methylophilyus methylotrophus is a bacterial species that produces single cell protein. It is used as a food supplement by humans as well as animals. 
Chlorella is a single-celled green algae belonging to the phylum Chlorophyta. It is rich in proteins that contain essential that amino acids needed for tissue building and maintenance of metabolic pathways. Hence it is consumed as a source of protein.
b) Soil
The microbes such as protozoans, fungi and bacteria in soil help in the breaking down of the complex organic matter. Hence they act as decomposers and form a part of Detritus food chain. This food chain helps in soil replenishment by adding nutrients to the soil.

Thank you Promoter of a new genetically modified variety of rice stated the following in a letter to the editor: Genetically modified (GM) rice known as "golden rice" has been produced. The rice is somewhat yellow in color due to the same pigment that gives carrots and sweet potatoes their color. This pigment is beta-carotene, which can be converted by the body into Vitamin A. Vitamin deficiency is the cause of 500,000 cases of irreversible blindness each year. By growing the new GM rice and making it widely available to people in poor countries, these cases of blindness could be avoided. Consider the various stakeholders listed below. Identify possible perspectives (either in favor or against) each would have regarding the genetically modified rice. The first one is done for you (marked). Stakeholder Perspective Crosses between the golden rice and existing varieties of rice may occur. The offspring may become pests in the natural environment.
