What physical factors affect marine organisms?
Across
- 3. obtains most of its body heat from its surroundings
- 8. when water becomes too high in nutrients from runoff and causes algae blooms
- 13. generates heat internally
- 15. higher concentration of solutes on the outside of a barrier
- 16. nonliving
- 17. does not require oxygen
- 18. movement of water across a semipermeable barrier in response to differences in solute concentration on either side
- 20. a dissolved substance
- 21. an acronym for the amount of oxygen dissolved in seawater
- 22. drying out
Down
- 1. all of the organic and inorganic materials that an organism needs to metabolize, grow, and reproduce
- 2. lower concentration of solutes on the outside of a barrier
- 4. internal balance of physical factors that keeps organisms alive
- 5. this type of waste is produced in all organisms and must be removed from cells
- 6. Living portion of an organism’s environment
- 7. requires oxygen
- 9. same concentration of solutes on either side of a barrier
- 10. tiny photosynthetic organisms that float in ocean currents
- 11. all of the chemical reactions that occur in cells
- 12. this force increases exponentially as an object descends deeper into the ocean under water
- 14. a system composed of living organisms and their nonliving environment
- 19. the concentration of dissolved inorganic salts in water
