Across
- 2. an organism that creates its own food using simple inorganic substances and an external energy source
- 6. any organism, cell, or process that uses light energy to convert carbon dioxide and water into usable sugars and oxygen
- 9. a solution or environment that has a higher concentration of solutes like salt or sugar and greater osmotic pressure than another fluid, such as the inside of a cell
- 11. the three main components of food carbohydrates, proteins, and fats that your body needs in large amounts to provide energy and maintain proper function
- 12. spontaneous movement of water molecules through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration
- 13. chemical substance found in food that an organism uses to live, grow, maintain its body, and reproduce
- 14. the physical process by which particles move from an area of higher concentration to an area of lower concentration due to their random thermal motion
- 15. a living organism that cannot make its own food and must get energy and nutrients by eating other plants or animals
- 16. substance or compound is generally a chemical structure that lacks carbon-hydrogen bonds
- 17. an organism that gets its energy by oxidizing chemical compounds instead of using sunlight
Down
- 1. grown and processed without synthetic fertilizers, man-made pesticides, genetic engineering, or irradiation
- 3. organisms that use light energy from the sun to convert inorganic compounds into organic food through photosynthesis
- 4. organisms that live on the outer surface or skin of a host organism to feed and survive
- 5. organisms that get their energy and food by feeding on dead and decaying organic matter
- 7. parasites that live inside the body of a host organism
- 8. solution has a lower concentration of solutes and a higher concentration of water than another solution
- 10. organisms that get both their energy and carbon by consuming preformed organic compounds
