Lingo…Basically, What You
are EXPECTED TO KNOW
at the end of this unit!
Each objective will be covered in class and you
are responsible for knowing this information
for the Ecology Test.
SB4: Students will assess the dependence of all organisms on one another and the flow of energy and
matter within their ecosystems.

9. What causes competition?
10. What is spatial distribution?
11. What are types of decomposers and the role they play in the environment?
12. Compare and contrast a niche and a habitat.
13. Describe the three types of symbiosis and give at least one example for each.



Arranging components of a food chain according to energy flow.
Comparing the quantity of energy in the steps of an energy pyramid.
Explaining the need for cycling of major nutrients (C, O, H, N, P).
1. What is a producer/autotroph? Give an example.
2. What is a consumer/heterotroph? Give an example.
3. What do the levels on the trophic pyramid represent?
4. Define biomass.
5. What is the primary source of all energy?
6. Explain the 10% energy rule. (how much energy is available at each succeeding level in an energy
pyramid).
7. Draw and identify the trophic levels in an energy pyramid.
8. Describe the relationship between plants and nitrogen fixing bacteria.
9. What is nitrogen fixation and why is nitrogen fixation an important process?
10. Explain why energy flow is one-directional.
11. Explain how nutrients are recycled. Give an example with your explanation.
SB4c. Relate environmental conditions to successional changes in ecosystems.
1. What is the difference between primary and secondary succession?
2. What is a pioneer species? Give an example.
SB4d. Assess and explain human activities that influence and modify the
environment such as global warming, population growth, pesticide use, and
water and power consumption.
1. Draw a logistic model of population growth graph. What does it represent?
2. Draw an exponential model of population growth graph. What does it represent?
3. What does zero population growth mean? Draw what it might look like on a graph.
4. What is a limiting factor? Give an example.
5. What is carrying capacity?
6. What is the difference between density-dependent & density-independent limiting factors? Give
examples of each.
7. What is the difference between renewable and non-renewable resources? Give 2 examples of
each.
