Carbon and the Earth
Across
- 3. The movement of substances that involves Earth’s physical features, such as the rock cycle, plate tectonics, or volcanism
- 6. A monosaccharide sugar, C6H12O6,that is produced in photosynthesis and used during cellular respiration for energy production
- 10. The amount of biomass present at each trophic level in a given area
- 13. The whole mass of air surrounding Earth; made up of 78% nitrogen, 21% oxygen, and other trace gases
- 14. The sum of all the life on Earth
- 15. A gas found in Earth's atmosphere produced by animals during respiration or during burning(combustion); used by plants for photosynthesis
- 20. One of the primary substances that make up
- 21. Containing the element carbon
- 23. The process by which autotrophic organisms capture light energy to convert carbon dioxide and water into glucose and oxygen, thereby storing some of the captured energy in chemical bonds
- 24. The process by which cells convert chemical energy stored in various compounds, such as sugars, into useful energy for cellular processes; may be aerobic or anaerobic
- 25. and cannot be chemically broken down or
- 26. A substance composed of multiple elements combined in fixed proportions
- 27. An organism’s position on a food chain
Down
- 1. The conversion of inorganic carbon to organic molecules
- 2. A naturally occurring element of Earth that is an essential building block of organic compounds
- 4. The ending substance(s), written on the right side of the chemical reaction arrow, that are created during a chemical change
- 5. Organisms such as bacteria and fungi that break down the remains of dead plants and animals without need for internal digestion
- 7. All water on Earth, including oceans, surface water, groundwater, and glaciers
- 8. A biomolecule that contains hydrogen, carbon,and oxygen in a 1:2:1 ratio and that is used as a primary energy source and structural support
- 9. The primary molecule used by cells to store chemical energy for use in cellular processes
- 11. Matter that does not contain carbon
- 12. The starting substance(s), written on the left side of the chemical reaction arrow, which will be destroyed during a chemical change
- 16. The movement of carbon in and among the abiotic environment and living things
- 17. The process of breaking down a substance into its smaller components of organic matter; the process of decaying
- 18. The portion of the Earth system that includes Earth’s interior, rocks and minerals, landforms,and the processes that shape Earth’s surface
- 19. An organism that obtains its energy from an abiotic source, such as sunlight or inorganic chemicals
- 22. into other substances; defined by the atomic number
