Q3.2. A guppy farmer currently rears a guppy population by first adding a few adults to a large pool with plenty of food and then
letting the population grow with NO resource limits. She would like to invest in a system that can produce guppies faster. Which
of the following will yield the best result for her, assuming all are plausible?
Buy a type of guppy with a birth rate three times higher than that of her current guppies.
Buy two more pools, and add the same initial number of guppies to all three pools.
Start with three times as many guppies in the one large pool she currently uses.
Triple the amount of food she adds to the one large pool as the guppy population grows.
