Answers
1
If an organism divides and produces an exact copy of itself, the organism
Has reproduced asexually
Must have a virus and be infecting its own cells
Must be a combination of two parents
None of the above
2
Humans
increase
carbon dioxide in the atmosphere and contribute to the carbon cycle by
planting trees to improve photosynthesis
combustion from driving cars
using more solar power electricity
conserving energy with alternative energies
3
At which point in the cladogram do you think would represent having wings?
Point A
Point E
Point C
Point B
4
Organisms that carry out photosynthesis would cause a
decrease
of which gas in the atmosphere?
water
ozone
carbon dioxide
oxygen
5
When deforestation occurs in an area, what immediate effect does this have on the
water
cycle?
There is less runoff water, but more transpiration
CO2 begins increasing in the atmosphere
Less water is returned to the air by transpiration
More water is returned to the atmosphere by transpiration
6

response to stimuli
9
Which of the following is
true
of density dependent limiting factors?

They impact big and small populations equally
10
The branch that NAMES and groups organisms according to their characteristics and history is
ecology
embryology
taxonomy
phlogeny
11
Based on the chart, which event would most harm the Georgia Black Bear population?
introduction of the bald eagle to Georgia (eats rodents)

12
Which is an accurate description of the growth of most natural animal populations?

an increase in predators
a decrease in disease
an increase in mating season
14
Water can be returned to the atmosphere through the leaves of plants by
transpiration
precipitation
evaporation
condensation
15
Carbon and Nitrogen Cycle Question
parasites
herbivores
predators
decomposers
16
Biologists use dichotomous keys to
estimate the degree of difference between organisms
analyze evolutionary relationships subjectively
evaluate the importance of characters
classify and name organisms
17
What is one
biotic
factor that affects the size of a population in the ecosystem?
average yearly temperature
average yearly precipitation
local geography
number of predators in an ecosystem
18
Which of the following is
NOT
something decomposers can break down in the carbon cycle?
scraps of discarded food
carbon dioxide found in the air
the bodies of dead plants and animals
waste products like urine or feces
19
Fish, their predators and the water, sunlight, and plants that they rely on would be considered
a biome
an ecosystem
a community
a population
20
Bacteria are involved in many steps of the geochemical cycles -- which steps are they not?
