• During a drought, many
different organisms try to
get water from a small
supply, resulting in….
• What is competition?
• Two organisms interact,
and both benefit from the
arrangement.
•What is mutualism?
• An interaction in which
one organism benefits,
but the other isn’t helped
or hurt in any way
• What is
commensalism?
• An interaction in which
one organism captures,
kills, and feeds on
another
• What is predation?
• An interaction in which
two organisms live
closely together
(parasitism is an example)
• What is symbiosis?
• From one trophic level to
the next, this is a good
estimate of how much
energy is LOST.
• What is 90%?
(careful! It didn’t ask
how much is passed to
the next level)
• A diagram showing the
complex feeding
interactions in a
community
• What is a food web?
• Which trophic level
would have the largest
biomass in an
ecosystem?
• What is the first trophic
level (autotrophs)?
• An organism that eats
both animal and plant
matter
• What is an omnivore?
• The two different
processes that producers
use to make
carbohydrates.
• What are photosynthesis
and chemosynthesis?
(Photosynthesis is by far
the most common)
• Assemblages of
populations that live
together in a defined
area
• What is a community?
• A community plus all
the abiotic factors
around it
• What is an ecosystem?
• A group of similar
ecosystems with similar
climate and dominant
communities.
• What is a Biome?
• The combined portions of
the planet in which all life
exists
• What is the Biosphere?
• All the organisms of a
particular species that live
in a defined area
• What is a population?
• The changing seasons
we experience are a
result of this
• What is the tilt of earth’s
axis?
–Causes changes in the
length of days and angle of
heating
• A particular chemical
substance needed by
living things that is in
short supply in an
ecosystem
• What is a limiting
nutrient?
• The average weather
conditions an area has
year-after-year.
• What is climate?
• This is the condition in
which gases in a planet’s
atmosphere, such as CO2,
retain heat
• What is the greenhouse
effect?
• This is a process in which
nitrogen gas in the
atmosphere is converted
into a form that living
things can use.
• What is Nitrogen
fixation?
• This says that two species
cannot occupy the same
niche in the same habitat
at the same time
• What is the
competitive exclusion
principle?
• The role or job that an
organism fulfills within
its ecosystem
• What is a niche?
• The area that an organism
inhabits is called this.
• What is a habitat?
• Name for a group of
organism so similar to
each other that they can
breed and produce fertile
offspring
• What is a species?
• This is a word for the
evaporation of water
from the leaves of
plants.
• What is transpiration?
• Two factors that effect
enzyme activity.
• What is pH and
temperature.
