  1. 3. Preserved remains of, or traces of, ancient organisms
  2. 8. Assemblage of different populations that live together in a defined area
  3. 11. the change in heritable characteristics of biological populations over successive generations.
  4. 12. an organism which produces its own food through photosynthesis
  5. 13. any of several living arrangements between members of two different species, including mutualism, commensalism, and parasitism.
  6. 18. an organism that mostly consumes decaying biomass, such as meat or rotting plant material.
  7. 19. a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter.
  8. 20. the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved.
  9. 22. a relationship between the two living species in which one organism is benefitted at the expense of the other.
  10. 25. Process by which organisms that are most suited to their environment survive and reproduce most successfully; also called survival of the fittest
  11. 27. an animal that feeds on flesh
  12. 28. Largest number of individuals of a particular species that a particular environment can support
  13. 29. a pattern of behavior in which animals travel from one habitat to another in search of food, better conditions, or reproductive needs.

  1. 1. one specifies being the ancestor of two or more species in the later period.
  2. 2. Part of Earth in which lifre exists, including land, water, and air or atmosphere
  3. 4. The movement of genes into or out of a population
  4. 5. How well an organism can survive and reproduce in its environment
  5. 6. Study of past and present distribution of organisms
  6. 7. the similarity of one organism (the mimic) to another (the model) that enhances the mimic's fitness through its effect on the behavior of a third party, the operator
  7. 9. Change or adjustment in structure or habits by which a species becomes better able to function in its environment
  8. 10. Selective breeding of plants and animals to promote the occurrence of desirable traits in offspring
  9. 14. The selection of mates based on heritable traits
  10. 15. a defense or tactic that organisms use to disguise their appearance, usually to blend in with their surroundings.
  11. 16. an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
  12. 17. Organism that relies on other organisms for its energy and food supply; also called a heterotroph
  13. 21. the ecological interaction between two or more species where each species has a net benefit.
  14. 23. Group of ecosystems that share similar climates and typical organisms
  15. 24. an animal that feeds exclusively on plants.
  16. 26. All the organisms that live in a place, together with their nonliving enviornment
  17. 27. Competition is an interaction between organisms or species in which both require a resource that is in limited supply.
