An ECOSYSTEM is the total community of living
organisms in a particular area plus the nonliving factors of
the environment.
A BIOME includes any ecosystems found in a regional area. (For
example, one geographic area may contain a freshwater pond, as well
as wetland swamps, and a deciduous forest, that all interact in the given region making up a
biome.)
BIOTIC factors of an ecosystem are all of its living components.
ABIOTIC factors are the nonliving components of the
ecosystem.
A TROPHIC LEVEL is the particular place an organism maintains in a food chain.
A FOOD CHAIN is a simple representation of the trophic levels in order from producers
through all levels of consumers, then decomposers.
A FOOD WEB is an illustration of the complex interrelationships between all
trophic levels where a particular organism may function in more than one trophic level.
PRODUCERS are the organisms in an ecosystem that harness energy (usually from the sun) and make it available as food to . . .
PRIMARY CONSUMERS who get energy by feeding on producers. They then become a
food source for . . .
SECONDARY CONSUMERS, etc.
DECOMPOSERS break down dead plant and animal material making the raw materials
available for producers to reuse.
BIOGEOCHEMICAL CYCLES function to recycle nutrients throughout the ecosystem.
Some examples. . .
Plants use Carbon Dioxide for photosynthesis and produce Oxygen. The oxygen is used in animal respiration and Carbon Dioxide is produced.
Water cycles throughout ecosystems via evaporation, rain, runoff, etc.
Nitrogen and Carbon are released from dead organisms by decomposers so that they may be reused by producers and cycle throughout the food web.
Which of the following would NOT be considered to be a biotic factor of a taiga
ecosystem?
A: bacterial decomposersB: deer and elk
C: coniferous treesD: short summers
In an aquatic marine ecosystem a killer whale feeds on krill (primary consumers), birds (third-
level consumers), and penguins (fourth-level consumers). What would be the best way to
illustrate these relationships?
A: food webB: food chain
C: photographsD: phylogenetic tree
Which of the following would not commonly be found in a desert ecosystem?
A: snakeB: bacteria
C: deciduous treeD: cactus
A food chain shows
A: the order of trophic levels of a particular ecosystem from producer to decomposerB: the complex web of interrelationships
between many trophic levelsC: the development of plants from seed to
adultD: the organisms that are not found in a
given ecosystem
A trophic level is
A: an organism's place in the food web.B: an organism's dwelling place in an
ecosystem.C: an organism's niche in an ecosystem.
D: an aquatic organism's place in the water column
In which ecosystem would you be most likely to find a coniferous tree?
A: temperate rain forestB: tundra
C: aquatic marineD: desert
Which of the following most accurately describes the carbon dioxide/oxygen cycle in terrestrial biomes?
A: plants produce oxygen and carbon dioxide that are used by animals in respiration
B: plants use carbon dioxide and produce oxygen, while animals use oxygen and produce carbon
dioxideC: animals produce carbon dioxide and oxygen
which are used by plants in photosynthesisD: plants produce carbon dioxide and use oxygen,
while animals produce oxygen and use carbon dioxide
One important function of bacteria in an ecosystem is to
A: build habitats for larger animalsB: kill lethal viruses
C: recycle nitrogen from dead organisms back into the food web
D: keep populations of large animals in check
