Question 1 Report

Which of the following organisms feeds both autotrophically and heterotrophically?
Answer Details
Euglena feeds both autotrophically and heterotrophically. Euglena is a unicellular organism with chloroplasts that allow it to carry out photosynthesis and produce its own food from sunlight, carbon dioxide, and water. However, it also has a primitive mouth-like structure that enables it to consume other small organisms as a supplementary source of nutrition. This feeding strategy makes Euglena unique compared to other organisms on the list, which rely exclusively on either autotrophic or heterotrophic nutrition.
