Question

14. Autotrophic nutrition occurs in
A Fungi
B plants
C Some protists and prokaryotes
D Both B and C​

Answer 1

Option D) Autotrophic nutrition occurs in plants and some protists and prokaryotes.

• Autotrophs are those that can make their food. They use water and minerals to make their food.
• Sunlight is the key ingredient in the conversion of inorganic to organic food.
• They are only dependent on themselves for their nutrition.
• Any organism that has a chloroplast organelle is an autotroph.
• Some protists and prokaryotes like cyanobacteria like blue-green algae, chlorella, Nitrobacter, etc. have autotrophic nutrition.
• All plants have chloroplasts and are autotrophic.

Answer 2

Answer:

D. Both B and C

Autotrophic nutrition occurs in plants and also in some protists and prokaryotes.

Explanation:

• There is an autotrophic mode of nutrition present in all green plants.
• Autotrophic organisms contain chlorophyll which helps to absorb solar energy from the sun.
• All plants are autotrophic because they can produce their food by the process of photosynthesis.
• Autotrophic plants use water, carbon dioxide, and sunlight to produce food.
• Protists are capable of getting their food in various ways, some protists are autotrophic while others are heterotrophic.
• Examples of organisms that possess an autotrophic mode of nutrition are cyanobacteria, red algae, green algae, and plants.
