Both organisms benefit from
living together.
Mutualism
An association where one organisms benefits, while the other neither benefits nor is harmed.
Commensalism
A long term relationship in which one organism obtains
nutrients from another.
Parasitism
A close relationship between two organisms of different species. Ex. microbes located in the
digestive tract.
Symbiosis
The use or defense of a resource by one
individual that reduces the availability of that
resource to other individuals.
Competition
The process by which inorganic materials
move from the atmosphere to soil, into
living organisms and back again.
Biogeochemical Cycles
T/F During ammonification, bacteria convert nitrogen gas into
ammonium compounds.
False
An increase in the ability of the
atmosphere to trap heat.
Greenhouse Effect
The cycle that photosynthesis and respiration are the
base for.
Carbon-Oxygen Cycle
Convert nitrogen gas (N2) into ammonium
compounds (NH4OH).
Nitrogen Fixation
The way of life of a species.
niche
The nonliving parts of the
environment.
abiotic factors
An ecological unit that includes all the
interacting parts of an environment in an area. Ex. a cave, a
pond
ecosystem
All the living organisms that inhabit an environment. Ex.
plants, animals, protists
biotic factors
The portion of Earth that sustains life. It
extends from high in the atmosphere to the bottom of the oceans.
biosphere
These are autotrophic
organisms that manufacture their
own food
producers
This means that it must consume
food to get energy.
Heterotroph
These heterotrophs can be classified into two main groups.
Primary and Secondary Consumers
This group of organisms break down dead tissue
and animal wastes.
Decomposers
What are the 4 classifications of consumers based on what they eat.
Herbivores, Carnivores, Omnivores, Scavengers
Interrelated food chains in an
ecosystem is call?
Food Web
A specific sequence in which organisms
get energy in an ecosystem.
Food Chain
Name that pyramid.
1,500,000 producers
1 scavenger
90,000 secondary consumers
200,000 primary consumers
Numbers Pyramid
Name that pyramid.
20,831 kCal producers
21 kCal secondary carnivore
383 kCal primary carnivore
3368 kCal herbivores
Energy Pyramid
Name that pyramid.
470 g/m2 producers
0.05 g/m2 scavenager
0.1 g/m2 carnivore
0.6 g/m2 herbivore
Biomass Pyramid
What are the 4 steps to the
water cycle?
Condensation
Precipitation
Transpiration
Evaporation
A state of severely reduced physiological
activity during the winter months.
Hibernation
Competition between
organisms of the same species
Intraspecific Competition
What are the 3 steps of the Nitrogen
cycle?
Nitrogen Fixation
Ammonification
Denitrification
A cycle of activity occurring every 24
hours. (ex. Pedals of a flower opening in the
morning and closing in the evening.
Circadian Rhythm
