2. a gas that contributes to the greenhouse effect by absorbing infrared radiation
3. chemical process in which oxygen is used to make energy from carbohydrates
5. the process by which nitrogen circulates among the soil, air, water, plants, and animals in an
7. equal concentrations of impermeable solutes on either side of the membrane and so the cell neither swells nor shrinks

10. a chemical compound made up of a carbon atom and two oxygen atoms
12. is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules,
13. nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again
16. long-term shifts in temperatures and weather patterns
18. is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions
19. the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land

1. a type of cellular transport in which substances such as ions and molecules move down their respective concentration
