Question

Which one of the following shows heterotrophic nutrition and mixotrophic nutrition?

• A. Heterotrophic nutrition- Rhizopus, Mixotrophic nutrition- Euglena
• B. Heterotrophic nutrition- Euglena, Mixotrophic nutrition- Rhizopus
• C. Heterotrophic nutrition- Pinus, Mixotrophic nutrition- Rhizopus
• D. Heterotrophic nutrition- Rhizopus, Mixotrophic nutrition- Pinus

Answer 1

The correct option is A Heterotrophic nutrition- Rhizopus, Mixotrophic nutrition- Euglena

Rhizopus is a genus of common saprophytic (feed on dead and decaying matter) fungi on plants and specialized parasites on animals that is heterotrophic organisms have to acquire and take in all the organic substances they need to survive.

A mixotroph or biotroph is an organism that can use a mix of different sources of energy and carbon, instead of having a single trophic mode on the continuum from complete heterotrophy at one end to autotrophy at the other e.g., Euglena an example. Thus, the correct answer is option A.
