Cabbage don't have storage roots or tubers, they are not a root vegetable. All the energy goes into producing flowers and seeds, if they are not cut down before.
Cabbage
A cabbage is a producer because it can make food with its green chlorophyll and it is a plant!
Yes, plants store extra food in the form of starch, which is produced through the process of photosynthesis. This stored energy can be used during periods of low light or when the plant needs extra nutrients for growth or reproduction.
The thrush eats the caterpillar, which in turn feeds on the cabbage plant. This forms a simple food chain where the energy is transferred from the plant to the insect, and then to the bird.
Lettuce stores extra food in their leaves, particularly in the form of carbohydrates and proteins. These reserves provide energy for growth and maintenance during periods of low sunlight or unfavorable conditions.
Dahlia store food in their tubers.
Plants store extra energy as starch, which can come in a wide range of forms. Potato plants store them in big underground tubers that we know as the edible vegetable, as do carrots, parsnips, turnips, etc. Apples, tomatoes, grapes and oranges are all other examples of energy storage sites. You may realise that these often correlate with the plant's seed location/vessel, for obvious reasons.
seed
Seeds store it in the endosperm.
purple cabbage is food
