Ecology Part B

3. Anaerobic respiration is respiration using electron acceptors other than molecular oxygen
7. a process that involves the movement of molecules from a region of lower concentration to a region of higher concentration against a gradient or an obstacle with the use of external energy
9. Climate change refers to long-term shifts in temperatures and weather patterns
11. the source of energy for use and storage at the cellular level
15. a type of membrane transport that does not require energy to move substances across cell membranes
16. is the net movement of anything generally from a region of higher concentration to a region of lower concentration
17. the long-term heating of Earth's surface
18. colourless, odourless, tasteless gas

1. is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth
2. a metabolic pathway that uses glucose to produce adenosine triphosphate (ATP)
4. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
5. the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions
6. an important heat-trapping gas, also known as a greenhouse gas,
8. describes how carbon moves between the atmosphere, soils, living creatures, the ocean, and human sources.
10. having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.
12. the membrane found in all cells that separates the interior of the cell from the outside environment.
13. a process in which the outputs of a system are circled back and used as inputs
14. occurs when greenhouse gases in a planet's atmosphere insulate the planet from losing heat to space, raising its surface temperature
15. the biogeochemical cycle that describes the transformation and translocation of phosphorus in soil, water, and living and dead organic material.
19. a type of sugar you get from foods you eat, and your body uses it for energy
