You cover food that's baking in the oven for several reasons. You can cover something to prevent your food from spilling onto the bottom of the oven or to prevent it from spitting juice/sauce onto the top of the oven. Another reason to cover your food is to keep the mositure in and prevent your food from drying out. The cover will trap the steam and cause it to turn back into condensation which creates a moist environment.
It can help to keep heat in to cook it faster, and a lid prevents food from splattering all over the inside of the microwave.
Because otherwise harmful bacteria and bugs/insects will be able to get on it, contaminate it and therefore make it unsafe to eat.
so that it does not go bad
Yes it protects it from germs/insects.
Refrigerated food should be covered to keep it from drying out and to keep odors from mingling in the fridge. Only if you want the food to dry out (like aging beef) should it be uncovered. Food in a pantry or cupboard should be covered to keep out dust or insects.
Food that wouldn't be eaten should be put in the fridge for preservation reasons. The fridge will help keep the food fresh with the low temperature. The covering of the food also helps by keeping air (oxidation) out from the food.
Keep food covered... Clean it really good put roach proof in areas behind fridge stove etc. keep it away from kids and pets. I wash meat styrofoam containers and use them. If your neighbors are nasty you will only keep them back you won't get rid of them. Keep your trash out food covered and dishes washed
One way to keep bees away from picnic food is by putting out bee traps around the area. Keep food covered and put away food right away.

Yes. As it will prevent the food drying out in the fridge.
