Across
- 2. Movement and reuse of nutrients in an ecosystem
- 6. Planting too many crops on the same land, leading to soil depletion and reduced fertility.
- 10. Water moving downward through soil
- 11. Fuel produced from living organisms (ethanol or biodiesel from corn, sugar cane, or vegetable oils)
- 13. The buildup of salts (like sodium, chloride, potassium) in soil or water bodies, making them saline (salty)
- 14. a fluid secreted by a living organism.
- 16. Clearing and burning areas of natural vegetation to plant crops. Each area is farmed for two or three years, then abandoned to regrow. The ash from fire fertilizes the soil.
- 17. A hoofed animal that digests plant-based food by fermenting it in a specialized stomach before chewing cud.
- 19. The practice of growing only one type of crop continously
- 21. Excess nutrients causing algae overgrowth in the water
- 23. The process of rocks breaking up into smaller and smaller fragments, through the action of water, substances dissolved in it, and living organisms, as well as temperature changes.
- 24. Farming practice of growing two or more crops together in the same field to maximize yield and reduce pests.
- 26. a type of agriculture where farmers grow just enough food to feed their families or small communities, focusing on self-sufficiency rather than generating profit for the market
- 27. Land is becoming dry and unproductive, like a desert
- 29. The intentional mating of plants or animals to enhance desired traits in the offspring.
Down
- 1. Man-made substances added to soil to supply nutrients and boost plant growth.
- 3. Changing an organism’s genes to give it new traits
- 4. Land that is unsuitable fo agriculture, can be applied to land for small scale farming and grazing
- 5. large-scale agricultural production of crops and livestock primarily for sale in markets to generate profit, using specialized methods to maximize output.
- 6. The state of a field or land that has too much of its vegetation eaten by herbivorous livestock. The vegetation is depleted to the point it cannot grow back
- 7. A substance that a plant needs in large amounts.
- 8. Any partially decomposed organic matter, such as loose gravel, silt, and sand partially decomposed organic matter
- 9. A fuel produced by chemical modification of vegetable oil, which can be used as a substitute for diesel fuel
- 12. Soil made up of particles of various sizes with a mixture of sand, clay, gravel, and a significant percentage of organic matter to create ideal soil for farming
- 15. The rock which is broken down to provide the mineral components of a particular soil.
- 18. Turning over soil to prepare land for planting
- 20. Any substance that is not from a living organism and does not contain carbon-hydrogen bonds Includes minerals, rocks, water, and metals, and is distinct from organic matter, which is derived from living things like plants and animals
- 22. Chemical substances used in agriculture to enhance crop production by controlling pests, diseases, weeds, or improving soil fertility.
- 25. fully decomposed organic matter, made up of a sticky substance which coats mineral soil particles.
- 28. The movement of broken-down particles of rock from one location to another, due to the movement of agents such as wind, water or gravity.
