Which of the following is an example of a living thing showing autotrophic nutrition? MCQ with Answer and Explanation

Spirogyra is a filamentous green alga containing chloroplasts, performing photosynthesis, hence autotrophic. Mushroom, Mucor, and Rhizopus are fungi, which are heterotrophic saprophytes or parasites. Autotrophs synthesize their own food using light or chemical energy. Spirogyra belongs to algae, classified under Plantae in five-kingdom classification. Its ribbon-shaped chloroplast aids in photosynthesis. This question tests the concept of nutrition modes.
