- 2. system body system that functions as a communication system andincludes the pituitary gland, the thyroid gland, the parathyroid gland, the thymus gland,the pineal gland, the pancreas, the adrenal glands, the ovaries, and the testes.
- 3. - Anything that eats or consumes other living organisms. All heterotrophs: they ingest food containing the sun’s energy. All Herbivores, Carnivores, Omnivores, Decomposers
- 8. - Also called: primary producer, producer, or PLANT. The beginning of a food chain
- 9. - The process of burning something
- 12. - the scientific study of interactions between organisms and their environments, focusing on energy transfer. The science of relationships
- 13. - Ingest (eat) food containing the sun’s energy. All Herbivores, Carnivores, Omnivores, Decomposers
- 15. levels - 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. cell the photosynthetic cells found in leaves of plants.
- 23. - the place in which an organism lives out its life
- 24. gravitropism the growth of plants in respect to gravity; roots are positivebecause they grow down and stems are negative because they grow up against gravity.
- 25. cell one of a pair of cells that function in the opening and closing of a plant’s
- 26. matter - anything that was alive and is now in or on the soil. For it to become organic matter, it must be decomposed into humus.
- 29. system the body’s largest organ that consists of skin, hair, and nails.
- 31. system body system that works to protect the body from infection anddisease and includes the skin, mucus, and white blood cells.
- 34. system body system that removes waste and excess water from the bodyand includes the lungs, skin, kidneys, and urinary bladder.
- 36. system - the above ground part of a plant, including stems, leaves, flowers, andfruits, which is responsible for photosynthesis, nutrient transport, and reproduction.
- 37. by changes in their shape.
- 38. - The total variety of organisms. The more different types of organisms = healthier ecosystem
- 39. - all living organisms inhabiting the Earth
Down
- 1. - 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.
- 4. system 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.Response organism’s reaction to a stimulus (a change in an organism’s environment)
- 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
- 6. the growth movement of a plant in response to light
- 7. factor - 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. - nonliving parts of the environment (i.e. temperature, soil, light, moisture, air currents
- 11. - Type of consumer that eats dead plants, animals and other organisms.
- 14. part of the plant that supports leaves, flowers, and fruits, transports water anddissolved substances from the roots to other parts of the plant.
- 16. - all autotrophs (plants), they trap energy from the sun. Beginning of the food chain
- 17. vascular plant tissue that transports water and dissolved minerals away from the roots through the plant.
- 18. - 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.
- 19. a tiny opening on the surface of a plant leaf or stem, surrounded by guard cells, which control the exchange of gases like carbon dioxide and oxygen between the plantand its environment.
- 20. system a network of tissues and vessels that carry blood and lymph throughthe body and includes the heart, arteries, veins and capillaries.
- 21. sink - Anything that absorbs more carbon from the atmosphere than it releases. Examples include: plants, ocean and soil
- 27. the sticky, receptive surface at the top of a flower’s female reproductive organwhere pollen grains land and begin the process of fertilization.
- 28. system the body system that works to control and coordinate all bodilyfunctions and includes nerve cells (neurons), the brain and the spinal cord.Ovule plant structure that develops into a seed when fertilized.
- 30. - the role a species plays in a community; its total way of life
- 32. species - 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.
- 33. organ of a plant that anchors it into the ground and takes in water and nutrients.
- 35. system the body system involved in producing offspring
