Unit 3

3. 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2
9. The study of relationships between biotic and abiotic things
11. Water can dissolve nutrients when in soil and carry nutrients down into groundwater or runoff into surface water
13. Organisms must eat to get energy
14. Energy is neither created or destroyed but only transformed
15. C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy(ATP)
16. Hold the energy flow of the ecosystem in balance and contribute to biodiversity (Removal leads to extinction of other species)
17. Total rate of photosynthesis in a given area

1. Contains:Atmosphere, Ecosphere, hydrosphere,and Lithosphere
2. With each energy transfer, less energy is available (10% rule)
4. herbivores, create biomass by eating plants, growing bigger and reproducing more herbivores which support carnivore populations
5. The rate at which produces make USEFUL chemical energy
6. natural processes that provide life supporting services like clean water,timber,crops, and fisheries
7. Neg & Pos, Starts at one level and ripples to other trophic levels
8. Photosynthesis, most growth in ecosystems where plants use sunlight and nutrients to grow, adding biomass to ecosystem
10. Organisms that make their own energy
12. Sum of primary and secondary productivity minus what decomposers use
