Food plays a major role in every ethnic group's culture. Canadian food adds a sense of belonging to the those that enjoy it.
Plants are considered to be the major group of organisms that are producers because they can convert sunlight into energy through the process of photosynthesis. This ability allows them to produce their own food and serve as the foundation of many food chains in ecosystems.
Citrus is not a food group. However there is a fruit food group.
Grain is not a food group, grains belong to a food group - the "carbohydrates".
Actually fats has its own food group, people don't usually refer to it as much, but it is the oils food group (which includes food like frosting, mayonaise, butter, etc). Otherwise in the other five major food group (vegetables, fruits, meats and beans, grains, and dairy) meat and beans would have the most fats in its products.
Meat, Grains, Oils, Fruits, Vegetables, Dairy
A mushroom isn't in any food group, but if it had a food group it would be fungus.
