1. What is sustainable living? How could someone achieve sustainable living? Do you personally think you could reach sustainable living?
Sustainable living is a lifestyle that attempts to reduce an individual's or society's use of the Earth's natural resources and personal resources.
A person could use less resources and be less polluting.
I do not think i could reach sustainable living because i use a lot of natural resources.
2. Fossil fuels vs Renewable energy- compare and contrast the two forms of energy. Look at the cost financially to humans and environmentally to the Earth. Convince someone to conserve energy.
fossil fuels are non renewable
renewable energy can be remade
If you keep using all the non renewable resources, there will eventually be no more. But if you manage how much you use and
3. Recycle- what does it mean to recycle? means to reuse or reduce something Why should someone recycle? So we don't waste to much material. How long does it take for these to decompose?
a. Tin Can- 50 years
b. Glass Bottle- 1 million years
c. Disposable Diaper- 450 years
d. Wood- 1-3 years
e. Paper- 6 weeks
f. Plastic Grocery Bag- 10-20 years
g. Styrofoam Cup 1+ million years
h. Aluminum Can- 80-200 years
i. Cotton T-shirt- 1-5 months
j. Apple Core- 2 months
k. Did any of these surprise you? yes the styrofoam
Great Pacific Garbage
4. What is the Great Pacific Garbage Patch?
this area is a large and continuous patch of easily visible marine debris items such as bottles and other litter. What can we do here in Iowa to help decrease it, is it even possible?Don't litter.
Biomes of the world
Grassland biome- all across the world 20-70 degrees- pond
tropical rain forest biome- south america/africa lots of rain- tree
It is where nothing can survive do to low water oxygen levels.
Fertilizers and Chemicals cause this.
Ways to stop can be using less fertilizers and changing the time you put down the fertilizers so it doesn't wash down the river.
8. Define Keystone Species, give 2 examples; one a top predator and one not a top predator. Explain how their absence would affect the ecosystem
Keystone Specie is a plant or animal that plays a unique and crucial role in the way an ecosystem functions
Predator- Mountain Lion helps with animal control
Not a Predator- Humming bird helps pollinate plants
Competitive Exclusion- that two species competing for the same resource cannot coexist at constant population values, if other ecological factors remain constant.
Paradox of Plankton
10. Define the following terms and give 2 examples of each
a. Coexistence-a policy of living peacefully - married couple living together, 2 or more groups living together
b. Parasites- an organism that lives on or in an organism of another species, known as the host, from the body of which it obtains nutriment. - tapeworm, fleas
c. Mimicry- the close external resemblance of an organism, the mimic, to some different organism, the model, such that the mimic benefits from the mistaken identity, as seeming to be unpalatable or harmful.- Bumblebees with and without stingers, snake or caterpillar
d. Mutualism- a relationship between two species of organisms in which both benefit from the association.-rhinoceros or zebra, flower and bee
e. Commensalism- a type of relationship between two species of a plant, animal, fungus, etc., in which one lives with, on, or in another without damage to either.-Anemonefishes, Atlantic puffin
biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
humans can affect by burning fossil fuels and deforestation
12. What is global dimming? Where does it usually affect and why is it a problem?
is when clouds reflect the sun's rays back to space. This is being caused by fossil fuel use, which also creates global warming
happens all over and cause the earth to be colder
13. Explain the Greenhouse Effect. How do the carbon cycle and the greenhouse effect go together?
is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions.
They basically do the same thing.
threatened with extinction, pandas
they get killed off or they die on there own from food shortages or etc
It wouldn't be able to help the other species if it was extinct
Because they help us in away
15. Invasive Species- define invasive species; give 2 examples how do they affect the ecosystem they are now invasive too. How did the invasive species arrive to their new ecosystem?
are plants, animals, or pathogens that are non-native (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause harm.
16. At one time rainforest covered 14% of the Earth’s land surface; today rainforest only cover 6% today; why should a person care about the lost rainforest ground? Why are the rainforest being cut down? What would happen if they all disappeared?
They are being cut down for wood or to make housing area
If they all disappear then there will be no oxygen
Because it takes away the things that we need and cause resources to be used up more quickly and more pollution.
heat water food shelter
is any substance used to kill, repel, or control certain forms of plant or animal life that are considered to be pests.
kill of species
the crop you are trying to grow can be killed off because that pesticide that you are using can affect the plant growth
19. Interpret this quote. “If the bee disappeared off the face of the Earth, man would only have 4 years left to live.” Maurice Maeterlinck, The Life of the Bee
If one of things you need most disappears, you won't last much longer.
