slide3
Plants & Our Environment for 200

Deforestation and loss of plants in an ecosystem, reduces this process, which provides energy to an ecosystem.

slide4
Plants & Our Environment for 200

What is ‘photosynthesis’?

slide5
Plants & Our Environmentfor 400

Of the three major roles in the food web, plants serve as this.

slide6
Plants & Our Environment for 400

What are ‘producers’(or ‘autotrophs’)?

slide7
Plants & Our Environment for 600

Making new paper from old paperthrough recycling helps preserve forestsby reducing the number of these thatneed to be cut for wood to make paper.

slide9
Plants & Our Environment for 800

The three major reactants and two major products from photosynthesis.

slide10
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?

slide11
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 undersideof leaves, changes to vapor andis released to the atmosphere.

slide12
Plants & Our Environment for 1000

What is ‘transpiration’?

slide13
Animals & Our Environment for 200

In an energy pyramid, less energy is available to higher orders of these, which include animals.

slide15
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.

slide16
Animals & Our Environmentfor 400

What is ‘increase’ or ‘take over’?

slide17
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.

slide18
Animals & Our Environment for 600

What are food, water, shelterand open space?

slide19
Animals & Our Environment for 800

If a pesticide killed the grasshoppers, this animal in the food web below would be MOST affected next.

slide21
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.)

slide22
Animals & Our Environment for 1000

What is “Chordates are causing a decline in arthropods in the Chesapeake Bay”?

slide23
Cycles in Nature for 200

The cycle in nature that humans directly affect by burning fossilfuels and releasing carbondioxide into the atmosphere.

.

slide24
Cycles in Nature for 200

What is the ‘carbon cycle’?

slide25
Cycles in Nature for 400

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.

slide26
Cycles in Nature for 400

What is the nitrogen cycle?

slide27
Cycles in Nature for 600

Global warming is meltingpolar ice caps and glaciers, which directly affectsthis cycle in nature.

slide28
Cycles in Nature for 600

What is the ‘Hydrologic Cycle’or the ‘Water Cycle’?

slide29
Cycles in Nature for 800

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).

slide30
Cycles in Nature for 800

What are ‘sugars’ (or ‘glucose’ or ‘carbohydrates’)?

slide31
Cycles in Nature for 1000

What it is called when twoorganisms of different specieslive and work together.

slide32
Cycles in Nature for 1000

What is ‘symbiosis’ (or in this case, a specific type of symbiosis called ‘mutualism’)?

slide33
Life Around Us for 200

A coral reef is an example of one of these – a community of organismsand the abiotic elementsin their surroundings.

slide34
Life Around Us for 200

What is an ‘ecosystem’?

slide35
Life Around Us for 400

Loss of habitat increases this among populations within an ecosystem(it results when two or moreorganisms are seekingthe same resource).

slide36
Life Around Us for 400

What is ‘competition’?

slide37
Life Around Us for 600

Introducing an invasive speciesinto an ecosystem can affect the relationship in a food web among decomposers, consumers,and these.

slide38
Life Around Us for 600

What are producers?

slide39
Life Around Us for 800

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).

slide40
Life Around Us for 800

What is ‘eutrophication’?

slide41
Life Around Us for 1000

By burning fossil fuels, humansadd to the heat-trapping gasesin the atmospherewhich are called this.

slide42
Life Around Us for 1000

What are greenhouse gases?

slide43
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.

slide44
Grab Bag for 200

What are amphibians(or Amphibia)?

slide45
Grab Bag for 400

Due primarily to humans’ effecton our ecosystems, expertsestimate that this will happento 27,000 species every year.

slide46
Grab Bag for 400

What is go extinct?

slide47
Grab Bag for 600

This term applies to an organism’sphysical location and, most importantly,functional role (much like anoccupation—what the organismspecifically does) within an ecosystem.

slide48
Grab Bag for 600

What is a ‘niche’?

slide49
Grab Bag for 800

This biome is home to the largestterrestrial biodiversity. It isbeing destroyed in Latin Americato make way for cattleranching and farming.

slide50
Grab Bag for 800

What are forests or tropical forests?

slide51
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 fromthe atmosphere and are the largestproducer of oxygen.

slide52
Grab Bag for 1000

What is phytoplankton, plankton or algae?
