Which requires carbon dioxide,water, sunlight and chlorophyll.

The correct answer is (d) all of the above.
Explanation: Autotrophic nutrition refers to the process where organisms like plants create their own food using sunlight, carbon dioxide, and water, with the help of a pigment called chlorophyll.
Key points about autotrophic nutrition:
Photosynthesis:
This is the primary process used by autotrophs to convert sunlight, carbon dioxide, and water into glucose (food).
Chlorophyll:
This green pigment within plant cells is crucial for absorbing sunlight energy needed for photosynthesis.
