Question

The carbon and energy requirements of autotrophic organisms are met through the process of ______.
1. Photoautotrophs
2. Photosynthesis
3. Hibernation
4. Biosynthesis

Answer 1

Correct Answer - Option 2 : Photosynthesis

The correct answer is Photosynthesis.

• Autotrophic organisms are those that prepare their own food.
• The chloroplast helps in preparing food.
• They obtain energy from inorganic sources by converting light energy into chemical energy.
• Carbon and energy requirements of autotrophic organisms are fulfilled by photosynthesis.

• Organisms that generate energy using light are Photoautotrophs.
  • Essentially, photoautotrophs make their own food, which is how they can live and reproduce.
• Hibernation refers to a season of heterothermy that is characterized by low body temperature, slow breathing and heart rate, and low metabolic rate.
