Vocabulary Know the following words: population niche communityabiotic bioticbiodiversity ecosystemecology carrying capacity

2. What are the two factors that affect a biome’s climate? Temperature and precipitation 3. Why is the role of predators important? predators limit the populations of their prey

4. Competition is usually most intense between which organisms? organisms of the same species 5. What are examples of different types of competition? Over food/water resources, mates, living space

6. What methods are used to measure populations? track-mark-release = good for tracking migration patterns sample count = good when measuring very large populations over a large area 7. What are the elements that affect population size? Biotic potential, movement of individuals in/out of an area, birth and death rates

8. What is the ultimate source of energy that fuels life on Earth? the SUN 9. What are the different classifications of organisms in an energy triangle? Be able to give an example of each. Producer = plants Primary consumer (herbivore) = rabbit Secondary consumer (carnivore) = snake Tertiary consumer (omnivore) = raccoon

10. What are the different types of symbiotic relationships? mutualism, commensalism, parasitism 11. What is cooperative action in a species? Give examples. species work together; ants doing specific jobs, schools of fish swimming together, meerkats warning each other of danger 12. Know what the graphs that represent exponential growth and carrying capacity look like.

13. Know the characteristics of the following biomes: tundra desert temperate deciduous forest flowing aquatic tropical rainforest

14. List some of the invasive species in North Carolina. kudzu, slippery elm, zebra mussels 15. Why is biodiversity important? habitats with little biodiversity eventually crash and die out 16. How do humans impact the biosphere? deforestation, development, agriculture, mining, energy production (dams, etc.)

17. Know how to read and use the food web represented below.
