Study Notes
Energy and Material Requirements
- All organisms need energy and materials for survival, but methods of fulfillment vary.
- Autotrophs, such as green plants and certain bacteria, obtain simple food materials from inorganic sources (carbon dioxide and water).
Autotrophs vs. Heterotrophs
- Autotrophs synthesize their own food, playing a crucial role in the ecosystem.
- Heterotrophs rely on complex substances for energy and materials, requiring these substances to be broken down into simpler components for utilization.
Role of Enzymes
- Enzymes function as bio-catalysts to facilitate the breakdown of complex substances in heterotrophic organisms.
- The survival of heterotrophs is dependent on autotrophs, creating an interdependent relationship in ecosystems.
Examples of Organisms
- Autotrophs primarily include green plants and certain bacteria that engage in photosynthesis or chemosynthesis.
- Heterotrophs encompass animals and fungi, which cannot produce their own food and must ingest other organisms or organic matter.
