N the real world, many factors determine the numbers of organisms in any one population. yet, a theoretical organism called superfly with unlimited food and no mortality would show what type of growth?

Since this theoretical organism called a "superfly" does not die and has unlimited resources, the type of population growth for this particular species will be exponential. In plotting the graph of exponential growth, a J-shaped curve will be the result, starting from a steady logarithmic increase then eventually being vertical.
