Blood sugar comes from the foods you eat. Food is broken down into glucose in the digestion process
yes
Insulin is released into the body when blood sugar levels are high to bring it down a notch
Essentially, any foods with carbohydrates will raise blood sugar. This is why aside of cutting out all sources of sugar (aside of the occasional small "cheat"), an endocrinologist will recommed a low carb diet for a Type 2 Diabetic such as myself. I can't say I've come across a specific food that will actually lower blood sugar, however there are several high in fiber such as lima beans, oatmeal, the acidic properties of vinegar, foods rich in magnesium such as spinach and almonds. Cinnamon is an ingredient that's best listed as "may help lower blood sugar." However this may vary from person to person - I used to take cinnamon supplements and personally it had no effect on my glucose, but that's not to mean it wouldn't help others.
REALLY INFORM DR.BUT NOT TO CONCERN AS YET BUT WHAT FOODS WOULD HELP
Eat a lot of protein, and reduce refined carbohydrates, which cause an insulin spike driving down blood sugar levels.
The glycemic index of a food measures how fast the sugars in the foods are broken down and turned into sugar into the body. Foods with a high glycemic index are quickly broken down and turned into sugar in the body, quickly raising sugar levels and creating imbalances in insulin. Low glycemic foods release sugar gradually in the body, offering both more satiety and lower spikes in insulin. This results in both better blood sugar control and lower lipids floating around in the blood. A low glycemic diet is great for both diabetics and those who are watching their weight.
with type ones you must take insulin (medicine given in the form of shots) to control your blood sugar. In some cases of type 2 diabetes diet and exercise alone does not lower the sugar levels alone. A tablet form of medication will also be given to help bring sugar level down.
It depends on the cause of the high blood sugar. If the patient has type II diabetes, their blood sugar may remain high after an insulin injection because their cells are insulin resistant. Often, these patients will be placed on a drug that increases insulin sensitivity, such as Metformin.
It comes from food that the organism ate. Either from eating glucose it is a form of sugar or from eating other foods that are eventually broken down into sugar.

Glucose is a sugar that is in your blood stream. You need to keep this under control. Sucrose is a form of sugar that can be use by diabetics but they need to watch their total carbohydrates, as these break down into simple sugars.
