Autotrophic mode of nutrition in an organism depends upon:
Correct answer: C. Photosynthesis mode
- A. Saprotrophic mode
- B. Parasitic mode
- C. Photosynthesis mode
- D. Obligate mode
Explanation
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen. This process is vital for life on Earth, as it provides oxygen and is the foundation of the food chain. Autotrophic mode of nutrition in an organism depends upon the photosynthetic mode.

About Plant Nutrition and Transport
Plants require macronutrients and micronutrients for growth, and mineral deficiencies produce recognizable symptoms. Transport involves water and minerals through xylem by transpiration pull, cohesion and adhesion, while phloem translocates sugars from sources to sinks. Root pressure and transpiration are distinct mechanisms.
