Natural Selection

2. one species hunts, captures, kills and eats another species
5. two species live together closely
6. the differences in a population
7. one organism depends on another (host) but does not kill it
9. the timing of reproduction is different, causing speciation
10. animals that feed on plants, primarily insects
14. the organisms with the adaptation that helps them survive and reproduce is the most fit for the environment
15. two species evolve in response to each other
16. one species benefits and no affect on the other

1. a type of speciation that occurs when populations become seperated
3. populations rise and fall over a long period of time
4. the process by which traits that improve organisms chances for survival and reproduction are passed on more frequently
8. the process by which new species arise
11. no recognition among species because mating calls, songs, or dances are different which causes speciation
12. some organisms are better suited to their environment
13. both species benefit
