tự dưỡng
Definition
- Adjective (Biology):
- Autotrophic: Describes an organism capable of producing its own organic nutrients from simple inorganic substances, typically using light (photosynthesis) or inorganic chemical reactions (chemosynthesis) as an energy source. Plants, algae, and some bacteria are autotrophic organisms.
Usage Examples
- Adjective:
- Thực vật là sinh vật tự dưỡng vì chúng tạo ra thức ăn từ ánh sáng mặt trời. (Plants are autotrophic organisms because they produce food from sunlight.)
- Vi khuẩn lam trong hồ có khả năng tự dưỡng. (The cyanobacteria in the lake have autotrophic capabilities.)
Advanced Usage
- "Tự dưỡng quang hợp": Photoautotrophic, specifically referring to organisms that use light as an energy source for autotrophy.
- Cây cối là những sinh vật tự dưỡng quang hợp điển hình. (Trees are typical photoautotrophic organisms.)
- "Tự dưỡng hóa tổng hợp": Chemoautotrophic, specifically referring to organisms that use chemical reactions as an energy source for autotrophy.
