- Decomposers
- Break down complex materials in PC and SC
- Simple elements formed- release minerals that can be absorbed by plants
- Break down complex materials in PC and SC
- Producers
- Food chains
- Feeding relationship
- Producers eaten by PC, who are eaten by SC, who are eaten by TC
- Each stage is called a trophic level
- Arrows show direction of energy flow
- Each stage is called a trophic level
- Producers eaten by PC, who are eaten by SC, who are eaten by TC
- Feeding relationship
- Food Webs
- Do not rely on single food source
- Many FCs linked to form web
- Complex- one organism may be eaten by 20 different organisms
- Likely that all organisms in habitat will be linked to others in web
- Complex- one organism may be eaten by 20 different organisms
- Many FCs linked to form web
- Do not rely on single food source
