Across
- 3. The "job" or function that a particular plant or animal has in its community.
- 6. The constant process of the Earth transforming and becoming different. Change can be natural (e.g., weather, seasons, extinction) or caused by humans (e.g., pollution, climate change, habitat destruction, etc.).
- 8. Cycle This cycle includes evaporation, condensation, and precipitation.
- 9. The protection of animals, plants, and natural resources. Conservation also includes the careful use of natural resources (such as trees, oil, etc.) to prevent them from being lost or wasted.
- 10. All the different plant and animal populations interacting with each other in an ecosystem.
- 11. A person who studies plants and animals as they live in nature.
- 14. The coming of one thing after another, in order.
- 15. And Effect Cause and effect relationships are routinely identified, tested, and used to explain change
- 20. Cycle The cycle includes the breakdown of materials, both dead and alive, by the decomposers (fungi, bacteria, and invertebrates).
- 21. Animals active by day, such as birds or insects.
- 24. Non-living things in an ecosystem (sun, air, water, and minerals).
- 26. The interactions between two or more natural resources (SAMSPAW) that make life on Earth possible.
- 28. A biological community of interacting organisms and their physical environment.
- 30. Impact Recorded history, as well as chemical and geological evidence, indicates that human activities in agriculture, industry, and everyday life have had major impacts on the land, rivers, ocean, and air.
- 32. And Change Explanations of stability and change in natural or designed systems can be made by examining changes over time, and forces at different scales. Small changes in one part of a system might cause large changes in another part. Stability might be disturbed either by sudden events or gradual changes that accumulate over time.
- 35. The study of how plants and animals cycle due to climate and/or seasonal changes.
- 36. The process by which the surface of the Earth is moved downward by wind, water, ice, and other natural activities.
- 37. Cycle This cycle includes the transfer of carbon dioxide (exhaled by animals) into the plants for use in photosynthesis, and the transfer of oxygen to animals (as a byproduct of photosynthesis) from plants.
Down
- 1. The state of the atmosphere with respect to the wind, temperature, cloudiness, moisture, pressure, etc.
- 2. A physical or behavioral characteristic of a plant or animal that helps it survive in its natural environment
- 4. Animals active at or around dusk, dawn, or twilight.
- 5. Organisms such as fungi, bacteria, or invertebrates (FBI) that feed on and break down dead plant and animal matter.
- 7. The process by which plants make food (carbohydrates/sugar) from water, carbon dioxide, minerals, and the sun's energy.
- 12. A symbiotic relationship between two organisms in which both organisms benefit from the relationship (e.g., pollination of flowers by bees.
- 13. The number and variety of plants, animals, and other organisms found in different ecosystems around the world.
- 16. A symbiotic relationship between two kinds of plants or animals in which one obtains a benefit (such as food or shelter) from the other without damaging or benefiting the other organism (e.g., when an animal moves into an abandoned rodent hole).
- 17. A symbiotic relationship in which one (the parasite) benefits, while the other (the host) is harmed (e.g., a flea in a coyote, or mistletoe on an oak tree).
- 18. An organism that makes its own food through the process of photosynthesis (e.g., all green plants).
- 19. A ridge of high land dividing two areas that are drained by different river systems.
- 22. Web A series of organisms linked together by food energy, each organism eaten by the next one in the chain.
- 23. Cycle The series of stages in an organism, including birth, reproduction, death, and decomposition.
- 25. Change A long-term change in the Earth's climate, especially a change due to an increase in the average atmospheric temperature.
- 27. The accurate and detailed description of land surfaces (e.g., mountains, valleys, rivers, etc.).
- 29. Observed patterns of forms and events guide organization and classification. The prompt questions about relationships and the factors that influence them.
- 31. Living once or living things in an ecosystem (plants, animals, bacteria, and fungi
- 33. An organism that feeds on plants and/or animals.
- 34. And Matter Energy can be transferred in various ways and between objects. It can be tracked as energy flows through a designed or natural system. Matter is transported into, out of, and within systems.
