Plants & Our Environment for 200

Deforestation and loss of plants in an ecosystem, reduces this process,

which provides energy to an ecosystem.


What is ‘photosynthesis’?


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 forests

by 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 underside

of leaves, changes to vapor andis released to the atmosphere.


What is ‘transpiration’?

Animals & Our Environment for 200

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.


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”?

Cycles in Nature for 200

The cycle in nature that humans directly affect by burning fossil

fuels 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 nature

with 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 primary

usable form of energy that plantsproduce during photosynthesis).


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


What it is called when twoorganisms of different species

live and work together.


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.


What is an ‘ecosystem’?


Loss of habitat increases this among populations within an ecosystem

(it results when two or moreorganisms are seeking

the 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 is

the generation of large ‘blooms’ of algaewhich can in turn disrupt the

normal functioning of the ecosystem).


What is ‘eutrophication’?


By burning fossil fuels, humansadd to the heat-trapping gases

in the atmospherewhich are called this.


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?
