A Barrel Cactus is a producer, as it obtains energy from the sun to create its own food through photosynthesis.
There are a number of species of cacti that bend towards the sun but the best known are several varieties of barrel cacti.
No Sunflowers can not grow in the dessert. They are not adapted for that because they need moist soil. But cactus' live in the desert. A cactus is enabled to survive in hot and dry environments.
A cactus doesn't really need much water to survive, and unlike many other plants, a large amount of sun and temperature changes is something this plant is used to.

Sunlight helps a desert cactus to grow. It's needed for photosynthesis. The sun brings its light to the photosynthetic interaction. The cactus plant brings its water, dissolved nutrients, and chlorophyll. The photosynthetic interaction between the sun and the cactus produces energizing starches and sugars. The energizing photosynthetic products are needed to fuel all of the cactus' life sustaining activities, such as growth, fruiting, and flowering.
Please remove the barrel cactus [Ferocactus spp] babies by pulling or cutting across a jointed part. Let the cut callus over. Pot in potting mix with a top dressing of small washed grit. Keep temperature levels at 64 degrees F/18 degrees C, in sun or bright shade. Fertilize and water when the soil almost dries out, every 10-14 days during the growing season.
If they are soft it could be rot which means it has too much water and needs to be dryed out quickly, if the blotches are hard it could be the start of sunburn and so just move it out of the sun.
