Many organisms depend on the land as a food source. Seasons can affect the amount of food that is available to these organisms. How would a long, cold winter most likely affect a population of deer?

A long, cold winter can reduce the plants and other food deer depend on, while also making it harder for them to survive. With less food available, fewer deer are likely to survive, so the population will decrease. The deer might recover later, but that is not the most likely immediate effect asked about.
