Ecology Test Study Guide
STATION: Levels of Organization (7 min)
1. Find the cutouts with the Levels of Organization on them. Arrange them from smallest to largest & them
write them in the below:
Level of Organization
Definition
Example
Individual living thing
A group of the same species living in
the same area
Different populations that live
together in a defined area
Community and its nonliving
surroundings
The part of the earth that contains all
ecosystems
2. Match the definitions and pictures with the correct level in the ecosystem, then write them into the
table above.
STATION: Symbiotic Relationship (7 min)
1. Match the pictures with the symbiotic relationship they exemplify
Symbiotic Relationship:
Organisms:
write the name of the missing
organism
______________________
Draw a
or
for each organism
Symbiotic Relationship:
Organisms:
write the name of the missing
organism
__________________________
Draw a
or
for each organism
Symbiotic Relationship:
Organisms:
write the name of the missing
organism
Draw a
or
________________________
for each organism
2. What two processes allow humans and plants to live in a symbiotic relationship?
STATION: Population Dynamics (10 min)
1. Match the words with the definition and picture examples, then fill in this chart:
Word:
Definition:
Example(s): Just write the
words for the example
The number of individuals for a particular species
that the environment can carry or sustain
Leave blank
Has a greater effect on limiting the growth of a
population as the population gets bigger
Effect on limiting population growth has nothing
to do with the size of the population
When the population size increases rapidly with
no limit
Draw graph
When a population starts growing rapidly, but
then stabilizes as it hits carrying capacity
Draw graph
STATION: Food Chains/Webs & Energy (12 min)
1. Looking at the food web at the station, identify what organism(s) the owl eats:
2. Write one of the food chains from the food web below (use the chain that includes the deer):
Organism 1:
Organism 2:
Organism 3:
Organism 4:
Food Chain:
Bird
Fill in the missing organisms
Write 1 below each organism:
Primary producer, primary
consumer, secondary consumer
3. Place the organisms from the food web into the
Energy Pyramid below. Write producer, primary
consumer, secondary consumer, tertiary consumer
on the lines next to it.
4. Name a secondary consumer:
5. If the producers have 2500 kJ of energy, how much
energy will the secondary consumers get?
6. What happens to the 90% of energy that
doesn’t pass on to the level above?
STATION: Nutrient Cycles & Resources (7 min)
1. Using the completed Nitrogen Cycle as a reference, which organism is the only living thing that can
take Atmospheric Nitrogen and perform a process called “Nitrogen Fixation” it so that it is usable to
living things?
2. Using the diagram of the Carbon Cycle as reference, tell the impact that deforestation would have
on the amount of Carbon in the atmosphere:
3. What effect would burning fossil fuels have on the amount of carbon in the atmosphere?
4. What effect does increase in farming to feed meat to more people have on the amount of carbon in
the atmosphere?
STATION: Greenhouse Gases (7 min)
1. List the 4 greenhouse gases:
2. Describe the greenhouse effect
3. Using the word bank to fill in the blanks and describe how the burning of fossil fuels contributes to global
warming
Word bank: global warming, fossil fuels, greenhouse, temperature, CO2, heat
(some words are used more than once)
Burning fossil fuels adds the _________________ gas __________________ to the atmosphere. More
__________________ in the atmosphere causes more _______________ to be trapped on the earth. More
heat on earth causes the global ___________________ to increase. This explains how burning _________
___________ contributes to _______________ _________________.
STATION: Succession (7 min)
1. Use the cut outs to complete the diagram, then write them in the Venn Diagram below:
STATION: Adaptations (7 min)
1.
Match the images of plants with the correct tropism. Write them below:
Image Description:
Pot on its side with roots growing down and plant growing
up
Flower growing towards light bulb, whether the light bulb is
above it or next to it
A plant that’s leaves close up when touched by a finger
Tropism:
A plant with roots growing towards a cup labelled “water
source”
2. What is an adaptation?
3. Look at the images of animals- choose 1 of the animals on the list & name an adaptation they have that
allows them to survive.
Animal
Adaptation
STATION: Classification and Cladograms (10 min)
1. Using the image at the station, what is the binomial nomenclature of the chihuahua?
2. Which Latin name in the binomial nomenclature is capitalized? (Circle one) the genus / the species
3. Using the 7 Dwarf Characteristics Chart, place the dwarfs in the correct box on the cladogram below:
