Ecology Part 2

3. source of energy for use and storage at the cellular level
5. the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmospheric, terrestrial, and marine ecosystems
11. a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
12. the oxidation of organic or inorganic substrates for ATP synthesis by oxidative phosphorylation using exogenously derived terminal (or alternate) electron acceptors other than oxygen
13. refers to long-term shifts in temperatures and weather patterns
14. type of sugar you get from foods you eat, and your body uses it for energy
15. the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
16. an important heat-trapping gas, also known as a greenhouse gas
17. biological occurrence where the output of a system amplifies the system
19. metabolic pathway that uses glucose to produce adenosine triphosphate

1. the biogeochemical cycle that describes the transformation and translocation of phosphorus in soil, water, and living and dead organic material.
2. a measure of the amount of carbon dioxide and other carbon compounds emitted due to the consumption of fossil fuels by a particular person, group, etc.
3. the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
4. the long-term heating of Earth's surface observed since the pre-industrial period
6. any external solution that has a high solute concentration and low water concentration compared to body fluids.
7. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct
8. a colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air
9. Passive diffusion across a cell membrane.
10. the process of movement of molecules under a concentration gradient
18. the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
