Question #1.) What is sustainable living? How could someone achieve sustainable living? Do you personally think you could reach sustainable living?

*Sustainable living is fundamentally the application of sustainability to lifestyle choices and decisions.

*By living simply and efficiently, and making everything we do use go as far as possible and achieve as much for us as possible.

*If i was to fallow my answer for the second question, yes, i would achieve sustainable living.

Question #2.) 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- Natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.

*Renewable energy- Energy from a source that is not depleted when used, such as wind or solar power.

*The daily activities if individual citizens account for more than half of the energy used in this country. Burning gasoline and fossil fuels leads to air pollution that contributes to global warming.

Question #3.) What does it mean to recycle? Why should someone recycle? How long does it take for these to decompose?

*To convert (waste) into reusable material.

*Recycling saves energy and by using recycled materials we save on energy consumption.

a.) Tin can- Around 50 years

b.) Glass bottle- 1,000 years

c.) Disposable diaper- 550 years

d.) Wood- 1 to 3 years

e.) Paper- 1 month

f.) Plastic grocery bag- 500 to 1,000 years

g.) Styrofoam cup- It doesn't decompose

h.) Aluminum can- 200 years

i.) Cotton t-shirt- 1 to 5 months

j.) Apple core- 2 months

k.) yes

Question #4.) What is the Great Pacific Garbage Patch? What can we do here in Iowa to help decrease it, is it even possible?

*The Great Pacific Garbage Patch is a collection of marine debris in the North Pacific Ocean.

* We as individuals can cut down on using plastic and use more eco-friendly materials.

* As a hole, can clean up the surrounding areas by recycling our bags, bottle, and etc...

Question #5.) Define 2 Biomes of the world, define an ecosystem found in each and explain the Biotic and Abiotic factors involved.

*Tundra: Is the coldest of all the biomes.

Noted for its frost molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons.

Biotic- Plants have adapted to the cold winters. Much wildlife such as: snowy owls, reindeer, white foxes, lemmings, and etc...

Abiotic- Strong winds, little precipitation, short summer days, very cold winters, and poor soil.

*Rainforest: Is an ecosystem that covers about 7% of the Earth's surface.

Found all over the world, but the majority are in South America (Brazil).

Biotic- 15 million different species of animals such as: sloths, anteaters, poison dart frogs, lemurs, bromeliads, and etc...

Abiotic- Fertile soil, water, rocks, much light, and the warm climate.

Question #6.) Choose any Biome; create a food chain defining the primary producer, primary consumer, secondary consumer, tertiary consumer, quaternary consumer, herbivore, omnivore, carnivore, scavenger, and decomposer.

*Grassland Biome

Primary producer- Grass

Primary consumer- Grasshopper

Secondary consumer- Mouse

Tertiary consumer- Snake

Quaternary consumer- Hawk

Herbivore- Giraffe

Omnivore- Ostrich

Carnivore- Leopard

Scavenger- Vultures

Decomposer- Woody shrubs

Question #7.) What are Dead Zones in the Gulf of Mexico? What causes this situation? What can be done to help stop them?

*An ares along the Louisiana- Texas coast, where water near the bottom of the Gulf contains less than 2 parts per million of dissolved oxygen.

* This is caused by nutrient enrichment from the Mississippi river particularly nitrogen and phosphorous.


Question #8.)
