Honors Chapter 6: Ecosystem
Balance Review
Consumers that actively
hunt other living organisms
are called_________.
predators
This is why new species are able
to form on islands
Large niche diversity, no
competition, no
predators
This might happen after a
forest fire
Secondary succession
The organism that is being
eaten
prey
Chance for a triple!!!!
Give an example of a
mutualistic relationship
Chance for a double!!
What two organisms make
up a lichen?
Fungi & Algae
T/F
Prey population follows predator
population in size
False
Chance for a double!!
What two factors determine a
terrestrial biome?
Temperature & Rainfall
What is the most diverse
terrestrial biome?
Tropical Rain Forest
A community that does not
undergo further succession is
called
Climax Community
One organism benefits the
other is harmed
Parasitism
Compare & contrast the desert
& the tundra
Both receive little rainfall
however desert is hot & the
tundra is cold
Bare Rock, Glaciers retreating
Primary succession
Chance for a home run!!!!!!
Describe the steps of primary
succession
Bare rock, lichens, soil
formation, grasses, shrubs,
seedlings, large mature
trees.
Chance for a double!!
Give an example of
commensalism
Why are there so many birds in
an island community
B/C they can get there easier
than other animals b/c of flight
T/F
If an ecosystem goes out of
balance, it cannot adjust to
regain the balanced state.
False
Chance for a double!!
Give an example of a parasitic
relationship
75% of Earth’s biomass is
contained in
forests
An increase in a predator
population will directly result in
A decrease in the prey population
Chance for a home run!!!!!!
Describe the difference between predation
& parasitism
When would you find
populations of host organisms
parasitized?
When they are overcrowded
Chance for a triple!!
Describe the Chaos theory
An organism that feeds on the
body fluids or tissues of
another organism but does not
kill it is called a
_________________.
Parasite
Name the three different types
of forests
Deciduous
Coniferous
Rain
Which biome do you live in?
Deciduous Forest
Chance for a homerun!!!
What are two theories that explain how the
dinosaurs became extinct?
Large comet or asteroid &
Changing climate
Which stage of succession has
a high evaporation rate?
Grass
Chance for a triple!!
Describe the process of
aquatic succession
Which stage of succession is
more biodiverse?
Forests
T/F
Most communities never reach
a climax stage
TRUE
Any relationship in which two
species live closely together &
at least one species is
benefitting.
Symbiosis
