  1. 4. An organism that obtains its energy from an abiotic source, such as sunlight or inorganic chemicals
  2. 7. Organisms such as bacteria and fungi that break down the remains of dead plants and animals without need for internal digestion.
  3. 8. All water on Earth, including oceans, surface water, groundwater, and glaciers
  4. 10. A gas found in Earth's atmosphere produced by animals during respiration or during burning (combustion); used by plants for photosynthesis.
