Adaptation Unit Vocab SC08

Physical adaptations - physical traits that help organisms survive and reproduce Predator - an organism that live by preying on other organisms Competition- two species fight for a limited resource Extinction - when all members of a species die Protective coloration - coloring blends into the environment

6. Behavioral adaptations - what an organisms does to survive 7. Migration - seasonal movement of animals 8. Nocturnal - physical characteristics suited for nighttime activities 9. Diurnal - physical characteristics suited for daytime activities 10. Dormancy - plants enter a resting or inactive stage

11. Endothermic - animal maintains a constant body temperature despite changes in the environment 12. Ectothermic - animal maintains body temperature by getting heat from its environment 13. Estivation - animals become inactive in summer; high temperatures, low water 14.Hibernation - animals become inactive in winter; cold temperatures, low food 15. Seed dispersal - seed design allows it to travel to new locations

16. Symbiosis - a close relationship between species that benefits at least one of the species 17. Mutualism - a symbiotic relationship where both species benefit 18. Commensalism - a symbiotic relationship where one species benefits, the other is not affected 19. Parasitism - a symbiotic relationship where one species benefits, the other is harmed 20. Mutation - a change in the DNA making up a gene

21. Pollination - mixes up genes creating diversity in organisms 22. Invasive Species - a species not native to an area, that competes with native species 23. Natural Selection - animals better adapted survive and reproduce more successfully passing on their genes to following generations 24. Beak design - different beak shapes are suited for different food types 25. Adaptation - anything that helps an organism survive and reproduce
