The incorrect statement is- B. Pitcher plant shows saprotrophic nutrition as their leaves trap the insects.
- The mode of nutrition in which organisms obtain nutrition from dead and decaying organic matter is called saprotrophic nutrition.
- Mushrooms are saprotrophs in nature as they acquire their food by feeding on the dead and decayed matter.
- The pitcher plant is not saprotrophic, it is an insectivorous plant that acquires its food by trapping and then eating insects.
- In Cuscuta, chlorophyll is absent, hence, it is a heterotroph. Cuscuta has a parasitic mode of nutrition as they obtain nutrients by growing on other plants.
- Algae are autotrophs as they contain chlorophyll, hence, they can make their food in the presence of sunlight.
