I'm going to start stocking up on food for winter!
Better make sure to get stocked up on some food.
My family isn't getting enough food. I'm going to go hunting.
Skunks and snakes hibernate for the winter but squirrels hunker down in their den. The squirrels have to stock up on food before the winter begins in order to have enough food to last them throughout winter.
I didn't get enough food and now I'm starving!
I need to go hunting for my cubs but there isn't a lot of fish anymore.
If there is an over populated area the animals will suffer because there is only a limited amount of food.
