Plants & Our Environment for 200
Deforestation and loss of plants in an ecosystem, reduces this process,
which provides energy to an ecosystem.
Plants & Our Environment for 200
What is ‘photosynthesis’?
Plants & Our Environment for 400
Of the three major roles in the food web, plants serve as this.
Plants & Our Environment for 400
What are ‘producers’(or ‘autotrophs’)?
Plants & Our Environment for 600
Making new paper from old paperthrough recycling helps preserve forests
by reducing the number of these thatneed to be cut for wood to make paper.
Plants & Our Environment for 600
What are trees?
Plants & Our Environment for 800
The three major reactants and two major products from photosynthesis.
Plants & Our Environment for 800
What are water, carbon dioxide, and light as the reactants and oxygenand carbohydrates (or sugars or
glucose) as the products?
Plants & Our Environment for 1000
This is the name of the process by which moisture is carried through plants fromroots to small pores on the underside
of leaves, changes to vapor andis released to the atmosphere.
Plants & Our Environment for 1000
What is ‘transpiration’?
Animals & Our Environment for 200
In an energy pyramid, less energy is available to higher orders of these,
which include animals.
Animals & Our Environment for 200
What are consumers?
Animals & Our Environment for 400
This will happen to the population of an invasive species that is introduced into an ecosystem where it has no known
predators.
Animals & Our Environment for 400
What is ‘increase’ or ‘take over’?
Animals & Our Environment for 600
There are five main needs of animals including air (or ‘gases”). Name the other
four which are all affected whenhuman beings encroachupon on animal habitats.
Animals & Our Environment for 600
What are food, water, shelterand open space?
Animals & Our Environment for 800
If a pesticide killed the grasshoppers, this animal in the food web below would be MOST affected next.
Animals & Our Environment for 800
What are ‘frogs’?
Animals & Our Environment for 1000
Restate the following: “Humans are causing a decline in blue crabs in the Chesapeake Bay ” using “phyla-speak” (a phylum is the taxonomic rank below “kingdom” and above
“class”) by filling in the blanks in this statement:
“A ________ is causing a decline in _____________ in the Chesapeake Bay.”
(Remember, humans have a backbone and blue crabsare crustaceans; they have a hard exoskeleton.)
Animals & Our Environment for 1000
What is “Chordates are causing a decline in arthropods in the
Chesapeake Bay”?
Cycles in Nature for 200
The cycle in nature that humans directly affect by burning fossil
fuels and releasing carbondioxide into the atmosphere.
.
Cycles in Nature for 200
What is the ‘carbon cycle’?
Cycles in Nature for 400
Chemical fertilizers contain a large amount of ammonium and nitrates.
As a result, humans are directlyaffecting this cycle in nature
with the use of chemical fertilizers.
Cycles in Nature for 400
What is the nitrogen cycle?
Cycles in Nature for 600
Global warming is meltingpolar ice caps and glaciers,
which directly affectsthis cycle in nature.
Cycles in Nature for 600
What is the ‘Hydrologic Cycle’or the ‘Water Cycle’?
Cycles in Nature for 800
Producers (plants) take CO2 from the atmosphere and convert it to this usableform in the energy pyramid (the primary
usable form of energy that plantsproduce during photosynthesis).
Cycles in Nature for 800
What are ‘sugars’ (or ‘glucose’ or ‘carbohydrates’)?
Cycles in Nature for 1000
What it is called when twoorganisms of different species
live and work together.
Cycles in Nature for 1000
What is ‘symbiosis’ (or in this case, a specific type of symbiosis called ‘mutualism’)?
Life Around Us for 200
A coral reef is an example of one of these – a community of organisms
and the abiotic elementsin their surroundings.
Life Around Us for 200
What is an ‘ecosystem’?
Life Around Us for 400
Loss of habitat increases this among populations within an ecosystem
(it results when two or moreorganisms are seeking
the same resource).
Life Around Us for 400
What is ‘competition’?
Life Around Us for 600
Introducing an invasive speciesinto an ecosystem can affect the relationship in a food web among
decomposers, consumers,and these.
Life Around Us for 600
What are producers?
Life Around Us for 800
Agricultural run-off of fertilizers into water ecosystems can cause this (it is
the generation of large ‘blooms’ of algaewhich can in turn disrupt the
normal functioning of the ecosystem).
Life Around Us for 800
What is ‘eutrophication’?
Life Around Us for 1000
By burning fossil fuels, humansadd to the heat-trapping gases
in the atmospherewhich are called this.
Life Around Us for 1000
What are greenhouse gases?
Grab Bag for 200
According to the figure, this category of animals (birds, rodents or amphibians) has the largest percentage of species in the ‘Critically Endangered’ and
‘Endangered or Vulnerable’ categories combined.
Grab Bag for 200
What are amphibians(or Amphibia)?
Grab Bag for 400
Due primarily to humans’ effecton our ecosystems, experts
estimate that this will happento 27,000 species every year.
Grab Bag for 400
What is go extinct?
Grab Bag for 600
This term applies to an organism’sphysical location and, most importantly,
functional role (much like anoccupation—what the organism
specifically does) within an ecosystem.
Grab Bag for 600
What is a ‘niche’?
Grab Bag for 800
This biome is home to the largestterrestrial biodiversity. It is
being destroyed in Latin Americato make way for cattleranching and farming.
Grab Bag for 800
What are forests or tropical forests?
Grab Bag for 1000
The marine biome is the largest andone of the most important on Earth, in part
because it contains these organismswhich take in large amounts of CO2 from
the atmosphere and are the largestproducer of oxygen.
Grab Bag for 1000
What is phytoplankton, plankton or algae?
