Study Notes
Producers (Autotrophs)
- Green plants and some bacteria produce their own food through a process of manufacturing.
Consumers (Heterotrophs)
- Obtain their food from producers.
- Classified into three categories:
Consumer Classifications
- Primary consumers: Obtain energy by consuming producers.
- Secondary consumers: Obtain energy by consuming primary consumers.
- Tertiary consumers: Obtain energy by consuming secondary consumers.
Decomposers
- Comprised of bacteria and fungi.
- Decompose dead organic matter and convert it into simpler parts.
