There are two types of nutritions- 1) Autotrophic nutrition & 2) Heterotrophic nutrition. In AUTOTROPHIC NUTRITION plants make their food themselves. Like- Alovera etc. While in HETEROTROPHIC NUTRITION organisms depend on other organisms to obtain their food. Like-Cuscuta, yeast, lice, bacteria etc. Heterotrophic nutrition is further divided into 3 types- Holozoic, Saprotrophic and Parasitic Nutrition.

1.autotrophic nutrition
2.heterotrophic nutrition

AUTOTROPHIC NUTRITION

THE MODE OF NUTRITION IN WHICH MAKE ITS OWN FOOD ITSELF FROM SINGLE INORGANIC SUBSTANCES IS CALLED AUTOTROPHIC NUTRITION.
FOR EXAMPLE-GREEN PLANTS MAKE THIER OWN FOOD FROM CARBON DIOXIDE AND WATER IN  THE PRESENCE WATER  AND CHLOROPHYLL.

HETROTEROPHIC NUTRITION

THE MODE OF NUTRITION IN ORGANISMS THAT CANNOT MAKE THEIR OWN FOOD AND DEPEND ON OTHERS FOR THEIR FOOD IS CALLED HETROTEROPHIC NUTRITION.
FOR EXAMPLE-ANIMALS AND HUMANS DO NOT MAKE THEIR OWN FOOD.THEY EAT THE FOOD PREPARE BY PLANTS OR EAT THE FLESH
