Autotrophs and heterotrophs

4. Photosynthetic pigment contained inside the chloroplasts of green plants
7. Describes relatively simple molecules that do not contain carbon and hydrogen
8. Process in which green plants harness sunlight to produce organic compounds from inorganic ones
9. A chemosynthetic bacterium that produces methane (organic) from carbon dioxide and hydrogen
11. Organelle that is the site of photosynthesis
12. Process in which some autotrophic bacteria produce organic compounds from inorganic ones

1. Organism that produces its own energy-rich compounds from inorganic ones
2. Process in which the cells of organisms break down glucose to make energy available
3. A special kind of heterotroph that obtains its nutrients by secreting breakdown enzymes onto the dead and decaying matter on which it grows, before absorbing the digested material
4. Process in which autotrophic organisms incorporate carbon atoms into organic molecules
5. Organism that does not make its own organic compounds, feeding instead on other organisms to acquire these
6. Energy-rich molecule that is both produced in photosynthesis and a raw material for cellular respiration
10. A group of chemosynthetic bacteria that inhabit extreme environments
