I. Capturing the Energy of Life

1. All organisms require energy
2. Some organisms (autotrophs) obtain energy directly from the sun and store it in organic compounds (glucose) during a process called photosynthesis

6CO₂ + 6H₂O + energy --> 6O₂ + C₆H₁₂O₆

II. Energy for Life Processes

1. Energy is the ability to do work
2. Work for a cell includes growth & repair, active transport across cell membranes, reproduction, synthesis of cellular products, etc.
3. Work is the ability to change or move matter against other forces (W = F x D)
4. Autotrophs or producers convert sunlight, CO₂, and H₂O into glucose (their food)
5. Plants, algae, and blue-green bacteria, some prokaryotes, are producers or autotrophs
6. Only 10% of the Earth’s 40 million species are autotrophs
7. Other autotrophs use inorganic compounds instead of sunlight to make food; process known as chemosynthesis
8. Producers make food for themselves and heterotrophs or consumers that cannot make food for themselves
9. Heterotrophs include animals, fungi, & some bacteria, & protists
