Which one of the following is not applicable to human ?

The correct answer is Autotrophic.

Key Points

• Humans are heterotrophic organisms, meaning they depend on other organisms for their food and cannot produce it themselves.
• Unlike autotrophs (e.g., plants), humans do not have chlorophyll and cannot perform photosynthesis, the process of converting sunlight into energy.
• Humans are classified as omnivores, as they consume both plant-based and animal-based food.
• The term "autotrophic" refers to organisms like plants, algae, and some bacteria that produce their own food using sunlight, water, and carbon dioxide.
• Humans rely on consuming organic matter, which categorizes them as heterotrophs, not autotrophs.

Additional Information

• Autotrophs: Organisms that produce their own food through photosynthesis or chemosynthesis (e.g., plants, algae, and some bacteria).
• Heterotrophs: Organisms that cannot synthesize their own food and depend on other organisms for nutrition (e.g., humans, animals, fungi).
• Omnivores: Organisms that consume both plant and animal materials for energy and nutrients (e.g., humans, bears).
• Carnivores: Organisms that primarily eat other animals (e.g., lions, tigers).
• Photosynthesis: The process in autotrophs where sunlight, carbon dioxide, and water are converted into glucose and oxygen, enabling energy production.
