- 27. (stimuli) something that causes and organisms to respond
- 28. the rising of a body of water and its overflowing onto normally dry land usually due to an abnormal amount of rainfall
- 31. an organism that obtains energy by feeding on other organisms
- 33. the release of water vapor from the leaves of plants through the stomata on the bottom of leaves
- 35. a giant wave usually caused by an earthquake beneath the ocean

- 42. any natural event that occurs on earth and causes significant changes or damage to the earth's surface. May include storms, earthquakes, and volcanic eruptions.
- 46. a long period of dry weather or lack of rain (precipitation)
- 47. plant tissue that transports water and minerals from the roots to the leaves/flowers
- 50. a catastrophic event, not caused by human activity, that can upset the balance in an ecosystem; includes weather events such as hurricanes, floods, etc., earthquakes, volcanoes, etc.
- 52. a severe storm that develops over tropical oceans and whose strong winds of more than 120 km/h spiral in toward the intensely low-pressure storm center, can be catastrophic when it makes landfall
