Which video?
I suggest you watch the video rather than trying to mooch answers from someone else who may be taking your class.

Hmmmm. Did you see a video on this? Did it discuss four factors?
My training tells me that factors which affect population size are:
availability of food,
environmental (temp, space, water, etc)
birth rate vs death rate
predators
These may or may not have been given to you.
