Imagine you are sitting down in a café and have just ordered sausage, egg and chips. There are so many things to consider when you look at that plate of food.
Let's start at the "field".
Firstly - sausages. Are they pork or beef? Someone has bred and looked after the pig or cow that made them. They have cared for the animal, made sure it was well fed and healthy. It might have come from a herd of hundreds of cows or a small organic farm with only a few animals. It will contain cereals, which another farm has grown, and herbs and seasoning, from somewhere else again.
What about the egg? We know eggs come from chickens, but imagine the problem if you have to produce thousands of eggs every day. The chickens need to be housed and fed and kept in good health. On average, people eat almost 200 eggs a year - that's over 11 billion eggs in the UK alone. Quite a task!
And another farm again has grown lots of lovely potatoes, and helped to produce some vegetable oil to fry them in, so that you can have your plate of chips.
But once the pig and the cereals, the egg and the potato have all left the field, what happens next? There are many other elements to the agriculture and food industries to consider. Someone has created a recipe for the sausages. Someone has carried out market research to see how people like sausages to taste. Someone has designed the branding for the packaging, and someone else has sold that particular brand of sausages to the café you are sitting in. The factory where they produce the sausages has been inspected, to make sure it is clean, and safe.
And your eggs… how do you go about loading 10,000 eggs into a delivery lorry, without breaking them all?
And there is still more work to be done to get the food on to your fork. The café will have a chef who has learned how to prepare, cook and present your food to you. They have learned about making sure the food is stored and cooked well so it is safe to eat, and how to create a whole menu of food for us to choose from.
There are a huge range of industries and jobs involved in getting food from where it is grown to where we eat it. You can go to places like Scotland's Rural College (SRUC) to study a whole range of subjects, from agriculture and animal science, to hospitality and professional cookery, if you are interested in working in these industries.
But don't reach for the tomato sauce - we haven't got enough time to think about that too!
