ecology

3. Changes in the allele frequency of a population due to random sampling.
5. Gene transfer resulting from organisms moving from one place to another.
7. An example of this would be us sweating when it is hot or shivering when it is cold.
8. Principle that states that from generation to generation the allele and genotype frequency in a population would remain constant as long as there is no mutation, natural selection, or genetic drift involved.
12. Phenomenon when a plant is exposed to elevated levels of carbon dioxide their photosynthesis rates are comparable to that measured in lower carbon dioxide concentrations.
14. Force that is exerted on the cell wall from the water inside that makes the plant tissue rigid.
15. Organisms whose temperature is not controlled by the environment.
18. The opposite of conformers as they can regulate their internal environment and are not influenced by the external environment.
19. Their body temperature is dependent on the temperature of the environment.
20. Animals that eat dead plants and animals.
21. Changes in the genes or chromosomes that can be inherited.

1. Reversible change as a response to the changing environment.
2. Process where one species has diversified to be able to adapt to the different features in their environment.
4. Line where two places meet.
6. A stage in the life cycle of an insect where its development is temporarily stopped.
9. Gradient of change in the phenotypic character of organisms in a region.
10. Population, subspecies, or race that has adapted to the unique conditions in their environment.
11. The environment influences internal change in that organism.
13. Similar to hibernation although it occurs during summer or dry seasons.
16. Freshwater organisms whose bodies have a higher salt concentration than their environment.
17. Result of natural selection that helps the organism survive and later reproduce.
