Study Notes
Biomolecules
- Lipids have no monomer
- Carbohydrates monomer is 1=
- Protein monomer is 1=
- Nucleic acid monomer is 1=
Energy Flow
- Secondary consumer death leaves energy for decomposers
- Energy at a trophic level is 10% of the previous level (energy = X/10)
Photosynthesis and Cellular Respiration
- Matter is rearranged during photosynthesis
- Energy changes form during photosynthesis
- Autotrophs produce their own food
- Heterotrophs consume other organisms for food
Other
- Cells are bigger than biomolecules
- Matter required for sugar production comes from external sources
- Energy for sugar production comes from the sun
- Examples of autotrophs and heterotrophs are needed for further study
- Independent and dependent variables are critical for experimentation.
