Humans breathe in.. and out.. - ANSWER Breath in oxygen and out carbon dioxide
Trees absorb.. and release.. - ANSWER Trees absorb carbon dioxide and release oxygen
If we cut down a lot of trees what happens? - ANSWER We REDUCE the amount of OXYGEN
being produced.
If we populate the area with a lot of animals we.. - ANSWER Increase the level of C.D and
methane. BAD FOR THE AIR.
If trees or rainforests were destroyed what happens to the environment? - ANSWER
Increase level of C.D. In the air and decreased level of oxygen in the ocean. Trees are part of
the AIR balance.
City is industrialized with factories. What does this mean? - ANSWER Areas with factories
have less trees; less trees=less oxygen which affects the air, making it harder to breathe. The
quality of air and how it impacts respiratory health.
Which organism is the lowest level? - ANSWER Plants; they are living organisms.
,why are plants important for the ecosystem? - ANSWER Source of food for animals that eat
plants and plants also create oxygen.
How would environmentalists likely make to address the problem with the atmosphere? -
ANSWER To combat air pollution the city should plant many green trees; "problem w/ the
atmosphere" means pollution.
How do trees use photosynthesis to process sunlight? - ANSWER The plant takes energy
from the sunlight and spreads hydrogen into its parts, helping to create sugar, water, and
oxygen.
Correct order of a plant life cycle: - ANSWER Seeds, trees, flowers, fruits.
"Unknown species/trees" (weeds) what is so bad about these? - ANSWER The trees of the
unknown species may need less sunlight and nutrients/water to survive and can overtake her
orchard and prevent the apple trees from obtaining enough water and nutrients, which can
cause them to die out. They grow quickly, and easily ruin a beautiful garden with flowers.
If we cut down trees and populate the area with animals... - ANSWER Less oxygen and more
cd and methane
Photosynthesis - ANSWER The process by which green plants and some other organisms use
sunlight to synthesize foods from C.D and water. This process in plans generally involves the
green pigment chlorophyll and generates oxygen as a byproduct. TREE NEEDS SUNLIGHT OR
CAN DIE FROM THE IVY/WEEDS.
Nutrient life cycle of a farm: - ANSWER Nutrients present in the soil
Nutrients consumed by tree and shrub
Nutrients released back into the soil
,Soil breaks down the waste
Equlilibrium - ANSWER Opposing forces cancel each other out; think of water: maintain it in
the way we use and waste water: full bathtub with the water draining out at the same time that
the water is running into the bathtub.
Oxygen levels in the water support life and - ANSWER Have a significant impact on species
when oxygen levels drop.
sea levels - ANSWER Risen by 2.6 inches; if there are changes that disrupt the flow of the
water, like storms, it can create a storm surge that overflows boundaries. Rising sea levels
around the world due to global warming are part of what causes extreme weather like massive
flooding and destruction; hurricanes.
"Survival of the fittest" - ANSWER LIFE is very adaptable; the life form that is most able to
adapt to the environment will survive the best. The life forms that can best "fit" the new
environment, will survive.
metamorphosis - ANSWER the process of transformation from an immature form to an
adult form in two or more distinct stages. When a caterpillar builds a cocoon and turns into a
butterfly.
Scientific study uses 4 steps.. to examine the way these life cycles and relationships are... -
ANSWER Observation
Hypothesis
Experiment
Conclusion
, Symbiosis - ANSWER a mutually beneficial relationship between two different people or
groups or organisms. (Termites and gut bacteria: bacteria Lives off the food in the termite's gut
or myna birds eating fleas off the body of a rhino which helps them stay healthy; and the birds
are eating. But, they can harm them by pecking at their skin.)
Two things that could change the land: - ANSWER Natural phenomenon and human impact:
farming, drilling, mining.... (Agricultural development)
Agriculture - ANSWER the science or practice of farming, including cultivation of the soil for
the growing of crops and the rearing of animals to provide food, wool, and other products.
Natural phenomenon: - ANSWER A fact or situation that exists or happens naturally in the
universe. Earthquakes, volcanos, tsunamis...
Earthquakes happen from... - ANSWER Tectonic plates shifting against one another and
releasing a huge amount of energy. Under water it pushes the water above it outward creating
huge waves that cause mass destruction.
Areas that experience drought still experience erosion from the... - ANSWER Wind
Weathering can also be caused by.. - ANSWER Bacteria; "eater of rock"; the Straub culture.
Can turn non-carbon sources, such as iron, into energy.
Topography - ANSWER A description of surface features of land. Deserts in New Mexico, Ice
tundras in Alaska, Islands in Hawaii, heavy rainfall in Philippines and Indonesia.
Human civilization has had two types of impact... - ANSWER Agricultural (Nomads in the
River valleys, grew crops, formed cities, developed trade.) and population growth (Family,
forming cities.)
