physical rather than biological; not derived from living organisms.
abiotic
relating to, involving, or requiring free oxygen.
aerobic
relating to, involving, or requiring an absence of free oxygen.
anaerobic
a predator at the top of a food chain, without natural predators of its own.
apex predator
an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
autotroph
an estimate of its production of certain biological materials such as natural resources, and its absorption and filtering of other materials such as carbon dioxide from the atmosphere.
biocapacity
the variety of life in the world or in a particular habitat or ecosystem.
biodiversity
the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth’s crust
biogeochemical cycles
the representation of total living biomass or organic matter present at different trophic levels in an ecosystem.
biomass pyramid
a large naturally occurring community of flora and fauna occupying a major habitat
biome
is the worldwide sum of all ecosystems
biosphere
any material that originates from living organisms.
biotic
that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth.
carbon cycle
an animal that feeds on flesh.
carnivore
an association between two organisms in which one benefits and the other derives neither benefit nor harm.
commensalism
and or resources belonging to or affecting the whole of a community.
commons
an interacting group of various species in a common location
community
an interaction between organisms or species in which both require a resource that is in limited supply.
competition
the part that doesn’t change during the experiment
constant
a group in the experiment which a variable is not being tested
control group
a scientific test done under controlled conditions
controlled experiement
an organism whose ecological function involves the recycling of nutrients by performing the natural process of decomposition as it feeds on decaying organisms.
decomposer
what you measure in the experiment and what is affected during the experiment
dependent variable
any large, extremely dry area of land with sparse vegetation
desert
a remote volcanic island in Polynesia.
easter island
when the Footprint of a population exceeds the biocapacity of the area available to that population
ecological deficit
the match of a species to a specific environmental condition
ecological niche
the phenomenon which occurs when the demands made on a natural ecosystem exceed its regenerative capacity.
ecological overshoot
the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
ecology
a biological community of interacting organisms and their physical environment.
ecosystem
designed to show the biomass or bioproductivity at each trophic level in an ecosystem
energy pyramid
the group in an experiment that receives the variable being tested.
experimental groups
a cost or benefit of a good or service that in not part of the price for that good or service
externalities
