Living organisms require energy for essential processes, with autotrophs like plants using photosynthesis to convert light into energy, while chemoheterotrophs rely on organic molecules for energy through cellular respiration, facilitated by mitochondria acquired via endosymbiosis. Organisms are classified based on how they acquire carbon and energy, with photoautotrophs producing organic molecules and oxygen through photosynthesis, shaping the Earth's atmosphere over time.
Insights
- All living organisms require energy for essential functions like protein synthesis and DNA replication.
- Autotrophs, such as plants and cyanobacteria, use photosynthesis to convert light energy into chemical energy, while chemoheterotrophs rely on organic molecules for energy and carbon, with mitochondria being vital for cellular respiration.
