Across
- 5. ingestion of liquids, such as oils or molecules in solution (“drinking”)
- 6. produce organic molecules (“food”), like sugars, using CO2 as a carbon source that can be used by themselves and by heterotrophs
- 8. an organism that must obtain its carbon from organic molecules
- 11. any substance that MUST be provided to an organism
- 13. instead of light, inorganic molecules (no carbon) such as iron, sulfur or magnesium provide the energy to make their “food
- 14. organisms that feed on organic material from dead organisms
- 15. live within cells
Down
- 1. required in relatively LARGE quantities and play principal roles in cell structure and metabolism
- 2. ingestion of whole cells or large solid matter (“eating”)
- 3. present in much SMALLER amounts and are involved in enzyme function and maintenance of protein structure
- 4. an organism that gets carbon from CO2 & can make its own “food” NOT nutritionally-dependent on other living things
- 7. live in the organs and tissues
- 9. live on the body
- 10. unable to grow outside of a living host
- 12. derive nutrients from the cells or tissues of a living host; not beneficial to the organism losing the nutrients
