Across
- 1. - the long-term prevailing weather conditions at a given place
- 2. - the communities of organisms living in the benthic zone of an aquatic biome
- 5. - the study of how organisms interact with each other and their environment
- 7. zone - the bottom surface of an aquatic environment
- 8. zone - the narrow top layer of an ocean or lake, where light penetrates sufficiently for photosynthesis to occur
- 9. zone - the part of an ocean or lake beneath the photic zone, where light does not penetrate sufficiently for photosynthesis to occur
- 11. - dead organic matter
- 13. - a plot of the temperature and precipitation in a particular region
- 14. - pertaining to the living factors - the organisms - in an environment
- 15. - a narrow stratum of abrupt temperature change in the ocean and in many temperate-zone lakes
- 16. - a natural or human-caused event that changes a biological community and usually removes organisms from it; disturbances, such as fires and storms, play a pivotal role in structuring many communities
Down
- 1. - the uppermost vegetation layer in a terrestrial biome
- 3. - the transition from one type of a habitat or ecosystem to another, such as the transition from a forest to a grassland
- 4. - climate patterns on a very fine scale, such as the specific climatic conditions underneath a log
- 6. zone - the part of the ocean’s benthic zone between 2,000 and 6,000 m deep
- 8. zone - the open-water component of aquatic biomes
- 10. - nonliving; referring to the physical and chemical properties of an environment
- 12. - the mixing of waters as a result of changing water-temperature profiles in a lake
