Across
- 2. the large-scale, cross-border movement, dispersal, and mixing of plants, animals, microbes, and diseases around the planet, driven largely by human trade, travel, and migration
- 4. an autotrophic organism that creates its own complex organic food molecules (like glucose) from simple inorganic substances using light or chemical energy
- 7. a living organism that cannot manufacture its own food and must feed on other organisms or organic matter to get energy
- 10. a vertical cross-section of soil from the surface down to the bedrock that shows all of its distinct horizontal layers
- 11. an oceanographic and biological process where deep, cold, and nutrient-rich water rises toward the ocean surface to replace warmer, nutrient-depleted surface water
- 12. the continuous, natural process by which Earth's rocks change over millions of years among three main types: igneous, sedimentary, and metamorphic
- 13. the scientific study of the relationships between living organisms—including humans—and their physical environment
- 14. the capacity to do work or cause change
Down
- 1. the process by which a liquid turns into a gas or vapor at temperatures below its boiling point
- 3. the introduction of harmful substances into the environment
- 5. the capacity of ecosystems and biological systems to endure disturbances, maintain critical functions, and preserve biodiversity over the long term
- 6. any liquid or solid water that forms in the atmosphere and falls to the Earth's surface,
- 7. an interacting group of various species populations coexisting in a particular geographic area and time
- 8. a printed or computer-aided biological tool that helps scientists and researchers identify unknown organisms by guiding them through a series of contrasting observable characteristics
- 9. the radiant light and heat emitted by the Sun that is captured and converted into usable forms of energy, such as electricity or thermal heat
