Saprophytic: It is the method in which organism first convert the complex food into the simpler and then use them as food e.g., bacteria, fungi etc.
Parasitic nutrition: It is the method in which an organism lives in the body of another organism and get nutrients from them e.g., Plasmodium, worms etc.
DIFFERENCE BETWEEN AUTOTROPHIC AND HETEROTROPHIC NUTRITION - DEFINITION
Different organisms obtain food by different modes such as autotrophic and heterotrophic mode of nutrition. These modes of nutrition have some differences which are as follows
Autotrophic nutrition Heterotrophic nutrition
1. Organisms prepare their own food. Organisms depend on another organism for food.
2. It includes photosynthesis and chemosynthesis. It includes holozoic, saprotrophic and parasitic.
3. Organisms have chlorophyll pigment. Organisms do not have chlorophyll.
