Autotrophic nutrition requires Carbon dioxide (as in most cases).
Some autotrophs don't require Carbon dioxide...
Holophytic and autotrophic nutrition are almost the same thing. Photoautrophs can be called holophytes, which is most autotrophs, but some autotrophs produce food by chemical synthesis, i.e. not in the presence of sunlight. They are chemoautrophs and not holophytes. Similarly, holotrophic and heterotrophic are almost the same. All heterotrophs which are not saprophytic or parasitic are holotrophs as well.
It means they make their own food. Like, auto- is the greek work for self. For example, a tree is autotrophic, whereas a badger is heterotrophic, meaning it depends on other organisms for food. Humans are heterotrophs. Grass is autotropic. Get it?
Autotrophic organisms are plants that don't need an exogenous supply of organic nutrition. Autotrophic organisms make their food from inorganic compounds, e.g. nitrogen.
Carbon dioxide.
There are primary forms of nutrients, macronutrients and micronutrients. The three main classes of macronutrients encompass carbohydrate, protein, and fat. The forms of micronutrients are vitamins and minerals, and those are greater molecules that cells need to make power.
Carbon Dioxide is needed for plants to make food.

Carbon dioxide
Producers get the carbon dioxide they need to make food from the atmosphere. They take in carbon dioxide during photosynthesis, a process in which they convert carbon dioxide and water into glucose and oxygen using sunlight.
Ofcource you need carbon dioxide! Weather we like it or not, we produce it, since when we breathe, we take in oxygen, but when we breathe out, we take ou Carbon Dioxide!
Plants obtain the carbon dioxide they need for photosynthesis from the atmosphere.
Plants need carbon dioxide (CO2) gas to carry out photosynthesis, the process by which they make food using sunlight, water, and carbon dioxide. During photosynthesis, plants convert carbon dioxide into carbohydrates to provide energy for growth and reproduction.
