Second-level consumer

producers
Best way to represent a
large complex system (ex.
water cycle).
computer model
In which process do producers use
carbon from carbon dioxide to
produce other carbon-containing
molecules?
photosynthesis
What shape would the
carbon cycle be in a
physical model?
circular
Group of land ecosystems with
similar climates and organisms.
biome
Ponds and rivers are what
types of ecosystems?
Fresh water
Organisms that were brought
by humans from one part of
the world to another.
Exotic species
Overlapping food chains
in an ecosystem.
Food web

cold and dry.
tundra
Break down the remains
of dead organisms.
decomposers
Frozen soil in the tundra.
permafrost
Process by which a gas
turns to a liquid.
condensation
Movement of organisms
from one place to another.
(ex. Spider moved by wind)
dispersal
Changing free nitrogen
into a usuable form.
Nitrogen fixation
Eats only animals.
carnivore
Eats only plants.
herbivore
Eats both plants and
animals.

product of photosynthesis.
oxygen
Feeds on dead
organisms.
scavenger
Trees that lose their
leaves each year.
Deciduous trees
Biome that has many
grasses.
grassland
Shows energy moving from one
feeding level to another.
Energy pyramid
Organisms eating other
organisms in a series of events.
Food chain
Rain, snow, sleet, or hail
(anything wet falling to Earth).
precipitation
Process by which a liquid
changes to a gas.
evaporation
Where the fresh water of a
river meets the salt water
of the ocean.
estuary

rainforest.
Emergent layer
Leafy roof under the
emergent layer in a
rainforest.
