The main difference between Autotroph and Heterotroph: Autotrophs are organisms that produce their own food from inorganic substances using energy from sunlight or chemicals. Heterotrophs are organisms that obt
Autotroph vs Heterotroph — Comparison Table
| Basis | Autotroph | Heterotroph |
|---|---|---|
| Food Synthesis | Synthesize own food from inorganic materials | Cannot synthesize food; consume others |
| Energy Source | Use sunlight or chemical energy | Use energy stored in other organisms |
| Process | Photoautotrophs use photosynthesis | Obtain food through ingestion |
| Examples | Green plants, algae, photosynthetic bacteria | Animals, fungi, most bacteria |
| Dependency | Independent; need sunlight and minerals | Dependent on autotrophs for energy |
| Ecosystem Role | Producers forming food chain base | Consumers at various trophic levels |
Key Points
- Autotrophs are self-feeders; heterotrophs are dependent feeders
- All heterotrophs ultimately depend on autotrophs for energy
- Photosynthetic autotrophs produce oxygen as byproduct
- Classification into autotrophs and heterotrophs is fundamental to ecology
