2. What are biotic factors Living
3. How do we measure biodiversity Number of species in an area
4. What is secondary succession Succession where there was a previous community
5. How do we determine which trophic level to place an organism into Source of energy
6. What is mutualism Symbiosis, both benefit
7. What is a habitat Part of organisms niche, where they live
8. What is competitive exclusion Competition usually causes one species to die off
9. What is a population Same species in the same area at the same time
10. How does the water cycle work Precipitation, evaporation, condensation
11. What is a herbivore Eats plants, primary consumers
12. What are the types of field experimentation Observation, modeling, experimentation,
13. What is a detritivore Feed on decaying or dead matter
14. What is an ecosystem Al biotic and abiotic factors in an area
15. How does sunlight affect an ecosystem Abiotic, provides energy
16. How does water get released back into the cycle after a rainfall Evaporation, transpiration
17. Where does all the energy in the ecosystem start sun
18. What is a keystone species Organisms with unusually large effect on an ecosystem
19. How can organisms share a niche Niche partitioning
20. What is commensalism Symbiosis, one benefits one is unaffected
21. What is parasitism Symbiosis, one benefits one is harmed
22. How do we find a population’s density Divide number of individuals by area

24. Be able to describe types of survivorship curves Type I, high population decreases towards end, Type II, Initially high and drops quickly (prey)
25. What is the difference between immigration, and emigration Immigration organisms into a population, emigration organisms out of a population
26. How do we know if something is density dependent or density independent Independent- natural disaster, weather, human activities Dependent- competition, disease
27. Be able to interpret an exponential growth chart J shaped curve
28. What is a pioneer species First to live in a previously uninhabited area
29. What is ecology Study of how organisms interact with one another and their environment
30. What is biodiversity Number of living species in an ecosystem
31. What is a food web Interrelated food chains
32. What is the difference between primary producers, and consumers Producers- plants, consumers- herbivores, secondary consumers- carnivores
33. How can two species be in the same niche Can not, competitive exclusion
34. What is an ecological equivalent Organisms with the same niche in different ecosystems
