Chapter 3 Rapid Fire Review
1. What is transpiration?
evaporation of water from leaves of plants
2. In the Carbon Cycle, where does most of the carbon go? atmosphere
And in what state is carbon most commonly found? CO2
3. Distinguish between the flow of matter (biogeochemical cycles) and the
flow of energy through ecosystems. matter recycles and energy only
travels in one direction
4. Name one main source of carbon dioxide in the atmosphere?
burning of fossil fuels, respiration, volcanic eruptions, etc.
5. What is the difference between denitrification and nitrogen fixation?
denitrification is nitrates transform to nitrogen gas, nitrogen fixation is when
nitrogen gas transforms to ammonia (NH3)
6. What is one way that the phosphorus cycle differs from the carbon and
nitrogen cycle? phosphorus doesn't enter the atmosphere; no gaseous
state

Put the following levels of
organization within the biosphere in
order from largest to smallest:
ecosystem 3
biome 2
species 6
individual 7
biosphere 1
population 5
community 4
2
Now identify those levels with the appropriate
definitions:
a. A group of organisms so similar that they can
breed and produce fertile offspring. species
b. Collection of organisms that live in a particular
place, together with their nonliving, or physical,
environment. ecosystem
c. Group of ecosystems that have the same climate
and similar dominant communities. biome
d. Combined portions of the planet in which all life
exists. biosphere
e. An organism. individual
f. Group of individuals that belong to the same
species and live in the same area. population
g. Assemblages of different populations that live
together in a defined area. community

Match the definitions with the appropriate terms!
c. niche
b. pioneer species
a. parasitism
h. mutualism 1. physical and biological conditions in which a species lives and the way the species obtains what it needs to survive and reproduce
2. both species benefit from the relationship.
d. ecological succession
3. one species benefits by living in or on the other and the other is harmed.
e. secondary succession
f. commensalism
4. The series of predictable changes that occurs in a community over time. g. primary succession
5. Begins in areas with no remnants of an older community. It occurs on bare 6. occurs when a disturbance changes a community rock surfaces where no soil exists. without completely destroying it.
7. one species benefits and one is neither helped nor harmed.
8. The first species to live in an area of primary succession.

1. What type of growth is represented in this graph?
j curve or exponential
2. What caused the human population to really take off and
industrial revolution
increase?
3. What caused a decrease in population just before the
human population took off? bubonic plague
Is this a density­dependent or density independent
limiting factor? density­dependent
6
1. What type of relationship is demonstrated in this graph?
predator/prey
2. How are the increases and decreases in the moose population related
to the changes in the wolf population? inversely related to each other;
wolf increases then moose decreases and vice versa
3. List 3 other density­dependent factors that could have caused the rise
and fall of the wolf and moose populations. disease, food sources, and
living space
