1.
Biotic and abiotic factors: Define and give two examples of each. Also provide an
example of each listed below.
 Abiotic factor affecting a biotic factor
 Biotic factor affecting an abiotic factor
 Biotic factor affecting a biotic factor.
2. Made a table with the following information: producer, primary consumer, secondary
consumer, tertiary consumer, decomposers, detrivores, detritus. Define each term and
give two examples of each
3. Draw a food web with at least 2 different producers, 2 different primary consumers, 2
different secondary consumers, and 1 top predator. Label each tropic level. Draw arrows
in the direction of energy flow (include the sun).
4. Draw an ecological pyramid. Include 4-5 tropic levels and illustrate the 10% rule. Which
Law of energy does the 10% rule represent?
5. Define Gross Primary Productivity, Respiration, and Net Primary Productivity. What is the
formula for calculating? Give an example of a problem to show how to use the formula.
6. Draw the carbon cycle and indicate the following processes: photosynthesis, respiration,
decomposition, and combustion. Which processes are biologic? Which process must be
reduced to reduce climate change? What are the 2 major carbon sinks (storage)?
7. Draw the nitrogen cycle and include the following processes: nitrification, nitrogen
fixation, assimilation, ammonification, and denitrification. Include the legumes and
Rhizobium bacteria. Define each process (nitrification, nitrogen fixation, assimilation,
ammonification, and denitrification) What is the major reservoir of nitrogen?
8. Draw the water cycle and include the following terms: evaporation, transpiration,
condensation, precipitation, infiltration, percolation. What is the importance of trees /
forests to the water cycle?
9. Draw the phosphorus cycle. Include the term guano. What is unique about this cycle?
10. Draw the Geologic Time Scale (label the names of the Eras and Periods).
Include 1 major geologic and biologic event for each Period. Show when humans FIRST
came on the scene.
11. Make a table with the following information: Invasive species, keystone species,
foundation species, endangered species, threatened species, endemic species, generalist
species, and specialist species. Define each term, give characteristic of each, and include
at least 3 examples of each.
12. Make a table with the following information: Biodiversity, genetic diversity, species
diversity, and ecosystem diversity. Define and give an example of each.
