Deforestation and loss of plants in an ecosystem, reduces this process, which provides energy to an ecosystem.
What is ‘photosynthesis’?
Plants & Our Environmentfor 400
Of the three major roles in the food web, plants serve as this.
What are ‘producers’(or ‘autotrophs’)?
Making new paper from old paperthrough recycling helps preserve forestsby reducing the number of these thatneed to be cut for wood to make paper.
What are trees?
The three major reactants and two major products from photosynthesis.
What are water, carbon dioxide, and light as the reactants and oxygenand carbohydrates (or sugars or glucose) as the products?
This is the name of the process by which moisture is carried through plants fromroots to small pores on the undersideof leaves, changes to vapor andis released to the atmosphere.
What is ‘transpiration’?
In an energy pyramid, less energy is available to higher orders of these, which include animals.
What are consumers?
This will happen to the population of an invasive species that is introduced into an ecosystem where it has no known predators.
Animals & Our Environmentfor 400
What is ‘increase’ or ‘take over’?
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.
What are food, water, shelterand open space?
If a pesticide killed the grasshoppers, this animal in the food web below would be MOST affected next.
What are ‘frogs’?
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.)
What is “Chordates are causing a decline in arthropods in the Chesapeake Bay”?
The cycle in nature that humans directly affect by burning fossilfuels and releasing carbondioxide into the atmosphere.
What is the ‘carbon cycle’?
Chemical fertilizers contain a large amount of ammonium and nitrates. As a result, humans are directlyaffecting this cycle in naturewith the use of chemical fertilizers.
What is the nitrogen cycle?
Global warming is meltingpolar ice caps and glaciers, which directly affectsthis cycle in nature.
What is the ‘Hydrologic Cycle’or the ‘Water Cycle’?
Producers (plants) take CO2 from the atmosphere and convert it to this usableform in the energy pyramid (the primaryusable form of energy that plantsproduce during photosynthesis).
What are ‘sugars’ (or ‘glucose’ or ‘carbohydrates’)?
What it is called when twoorganisms of different specieslive and work together.
What is ‘symbiosis’ (or in this case, a specific type of symbiosis called ‘mutualism’)?
A coral reef is an example of one of these – a community of organismsand the abiotic elementsin their surroundings.
What is an ‘ecosystem’?
Loss of habitat increases this among populations within an ecosystem(it results when two or moreorganisms are seekingthe same resource).
What is ‘competition’?
Introducing an invasive speciesinto an ecosystem can affect the relationship in a food web among decomposers, consumers,and these.
What are producers?
Agricultural run-off of fertilizers into water ecosystems can cause this (it isthe generation of large ‘blooms’ of algaewhich can in turn disrupt thenormal functioning of the ecosystem).
What is ‘eutrophication’?
By burning fossil fuels, humansadd to the heat-trapping gasesin the atmospherewhich are called this.
What are greenhouse gases?
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.
What are amphibians(or Amphibia)?
Due primarily to humans’ effecton our ecosystems, expertsestimate that this will happento 27,000 species every year.
What is go extinct?
This term applies to an organism’sphysical location and, most importantly,functional role (much like anoccupation—what the organismspecifically does) within an ecosystem.
What is a ‘niche’?
This biome is home to the largestterrestrial biodiversity. It isbeing destroyed in Latin Americato make way for cattleranching and farming.
What are forests or tropical forests?
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 fromthe atmosphere and are the largestproducer of oxygen.
What is phytoplankton, plankton or algae?
THE NATURE GENERATION
A non-profit organization dedicated to inspiring environmental stewards
Visit online at www.NatGen.org and follow us on Facebook!
Through a generous grant from the
LUCK STONE FOUNDATION
We inspire a shared responsibility to create a positive outcome for the natural, built, and work environments.
And in cooperation with
LOUDOUN COUNTY PUBLIC SCHOOLS INVIRGINIA
Thank you to The Nature Generation board members and volunteers from
our sustainable corporate partners for dedicating their time and expertise to developing this kit.
