- 64. The meteorite theory is the most popular theory that explains the mass extinction of dinosaurs during this time period.
- 65. Observations that occur through DIRECT interaction with the population being studied.
- 66. Evaporation: change of liquid to a gas (water vapor)Transpiration: release of water vapor through the stomata of plant leaves Condensation: water vapor cooling and changing back to a liquid Precipitation: liquid that has condensed and is falling from the atmosphere as rain, sleet, snow, or hail
- 67. Animals are moving northward to cooler climates and migrating to higher elevations than before.
- 68. Only biome with 4 proper seasons
Down
- 2. Model that shows the available energy at each trophic level Only 10 percent of the energy at each trophic level is passed on to the next trophic level (90% of energy is lost)
- 4. Long cold winters, short wet summers
- 5. different genes & combinations of genes within populations
- 7. Chemicals in the air mix with water to form harmful pollutants
- 8. The role or function of an organism within its environment
- 9. Nitrogen is an essential component in amino acids, proteins, nucleic acids, and ATP Nitrogen gas makes up 78% of our atmosphere, but nitrogen gas is unusable to most organisms
- 10. Begins in a place that has no soil
- 11. how and where organisms are located Three types:Even (uniform) – not as common; occurs due to scarcity of resources Clumped – most common; safety in numbers, social interaction, mating and caring for young, resources are clumped. Random – rare
- 12. Different habitats, niches, species interactions in a particular biome.
- 14. This biome is the coldest and is frozen year round
- 15. Producers:Make their own food from sunlight. (autotrophs) Consumers:Must eat to gain energy (heterotrophs)
- 16. Simplified model that shows a single path for energy flow through an ecosystem
- 17. The predictable and gradual replacement of one plant community by another through natural processes over time
- 19. the rearing and the processing of cattle for food and byproducts
- 20. The only cycle that does not cycle through the atmosphere
- 22. Birth rate: number of births a population has in 1 year Death rate: number of deaths a population has in 1 year Growth rate: the difference between the birth and the death rate
- 23. Up to 85 km above earth Temperature decreases outside of ozone layer below Coldest layer of atmosphere
- 24. The total population divided into five-year age groups
- 25. the more dense a population is, the more effect the limiting factors will have
- 29. (eat primary)
- 30. Is a group of organisms of one species that interbreed and live in the same space at the same time
- 34. Highest biodiversity of all the biomes
- 36. Carbon also enters the atmosphere through cellular respiration. Fossil fuels (remains of ancient organisms) also release CO2 when they are burned.
- 39. What period was considered to have the burst of life but also contributed to the stores of carbon and fossil fuels?
- 41. eat to gain energy
- 42. The existence of a wide range of different types of organisms in a given place at a given time
