Lysogenic cycle spread viral DNA through the prokaryotic reproduction and thus it takes a long time in copying viruses. On the other hand lyctic cycle is an immediate and a fast process that allows making copies of viruses at a much faster rate than the lysogenic cycle but the cell (host cell) is destroyed.
However in lysogenic cycle the viral genome is introduced into the host cell genome thereby infecting it from inside.
More energy is needed to carry out the metabolic rate of a person ( the minimum amount of energy required to carry out all of the reactions needed to keep a person alive).
