Across
  1. 4. The concentration of a toxin (like a pesticide) in the tissues of organisms in a lower trophic level gets passed up to the next level when they get eaten. These toxins cannot be flushed out of the body, so each trophic level ends up with higher amounts of toxic material in their tissues.
  2. 7. The process of burning something
  3. 8. nonliving parts of the environment (i.e. temperature, soil, light, moisture, air currentsAutotroph Also called: primary producer, producer, or PLANT. The beginning of a food chain
  4. 10. photosynthetic cells found in leaves of plants.
  5. 11. Also called: primary producer, producer, or PLANT. The beginning of a food chain
  6. 14. An organism far back in geological history that 2 or more current organisms can be traced back to. For example: all birds can be traced back to small theropods (like a small T-Rex). So a common Ancestor for birds would be theropods.
  7. 16. the reduced genetic diversity in a new population caused by a small number of individuals being separated from a larger population. This will cause the new population to end up with a significant genetic difference from the original population.
  8. 20. Ingest (eat) food containing the sun’s energy. All Herbivores, Carnivores, Omnivores, Decomposers
  9. 22. any biotic or abiotic factor that restricts the existence of organisms in a specific environment. Amount of water, food, space, Temperature, Availability of mates
  10. 24. the scientific study of interactions between organisms and their environments, focusing on energy transfer. The science of relationships
  11. 28. all autotrophs (plants), they trap energy from the sun. Beginning of the food chain
  12. 29. The movement of genes from one population to another population of the same species. For example, White tailed Deer from one herd migrate into another herd's territory, and breed with the new herd. This helps improve and increase genetic diversity
  13. 30. A substance used for destroying insects or other organisms. Overuse can kill beneficial organisms in the soil. Overuse can runoff into rivers and streams killing beneficial organisms in the water
  14. 31. Anything that eats or consumes other living organisms. All heterotrophs: they ingest food containing the sun’s energy. All Herbivores, Carnivores, Omnivores, Decomposers.
  15. 32. physical or behavioral change that makes a species more likely to be successful in its environment.
  16. 33. the role a species plays in a community; its total way of life
  17. 35. the body system involved in breathing and gas exchange andincludes the nasal passages, the pharynx, the larynx, the epiglottis, the trachea, bronchi,the lungs, and the diaphragm.
  18. 36. the slow, gradual genetic change in an entire population of organisms over time
  19. 37. The ability of an organism to survive in its environment long enough to reproduce.
  20. 38. the body’s largest organ that consists of skin, hair, and nails.
  21. 40. Each link in a food chain is known as a trophic level. Trophic levels represent a feeding step in the transfer of energy and matter in an ecosystem. Goes from producer to consumer to decomposer
  22. 41. The total variety of organisms. The more different types of organisms = healthier ecosystem
Down
  1. 1. the place in which an organism lives out its life
  2. 2. Anything that absorbs more carbon from the atmosphere than it releases. Examples include: plants, ocean and soil
  3. 3. the growth of plants in respect to gravity; roots are positive because they grow down and stems are negative because they grow up against gravity.
  4. 5. Microscopic plants that float among the other plankton in the upper layer of the oceans. Phyto means plant or plant-like. So they go through photosynthesis. Often the primary producer for ocean food webs
  5. 6. body system that functions as a communication system and includes the pituitary gland, the thyroid gland, the parathyroid gland, the thymus gland.
  6. 9. one of a pair of cells that function in the opening and closing of a plant’s stomata by changes in their shape.
  7. 12. plant structure that develops into a seed when fertilized.
  8. 13. system that removes waste and excess water from the body and includes the lungs, skin, kidney.
  9. 15. the body system that works to control and coordinate all bodily functions and includes nerve cells (neurons), the brain and the spinal cord.
  10. 17. Type of consumer that eats dead plants, animals and other organisms.
  11. 18. the growth movement of a plant in response to light.
  12. 19. features in different species that perform similar functions but do not have the same structure (how it's made). These species do not have a common ancestor.
  13. 21. a non-native (from a different part of the world) organism that spreads and harms the environment, economy, or human health. They can be plants, animals, parasites, or diseases.
  14. 23. new species that appear suddenly in the fossil record
  15. 25. A particular gene is lost due to chance.This will cause the population to change, with some traits disappearing completely.
  16. 26. all living organisms inhabiting the Earth
  17. 27. body system that works to protect the body from infection and disease and includes the skin, mucus, and white blood cells.
  18. 34. anything that was alive and is now in or on the soil. For it to become organic matter, it must be decomposed into humus.
  19. 39. a taxonomic group that includes multiple species that are closely related and share common characteristics
