(a) The shift from grain to meat diets creates more demands for cereals. Why?

(b) A 250 kg cow produces 200 g of protein per day but 250 g of Methylophillusmethylotrophus can produce 25 tonnes of protein Name this emerging area of research. Explain its benefits.

(a) The shift from grains to meat diets create more demands for cereals because the humans consume meat which is obtained from animals such as goat, chicken, cow etc. These all animals are herbivores and they consume cereals and grasses for their nourishment. Also it takes 3-10kg of grain to produce 1kg of meat by animal farming.

(b) The name of this emerging area of research is Single Cell Protein. Single cell protein is used as the alternate source of proteins for animal and human nutrition. Single cell proteins are very advantageous as the microbes are grown in very large amount and they produce a large amount of proteins within short span of time. This protein can be consumed by animals and humans as the alternative source.

Hence, single cell protein is less time consuming, less product using and high yielding method. Also it helps in reducing environmental pollution because there is no misuse of products.
