1. What is sustainable living? How could someone achieve sustainable living? Do you personally think you could achieve this?
Recycle more, walk or take public transportation.
I could if I try. the real question is will I
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.
3. Recycle- what does it mean to recycle? Why should someone recycle? How long does it take for these to decompose?
Glass Bottle- 1,000,000 years
Disposable Diaper- 500-800 years
Paper- 1 month
Plastic Grocery Bag-
Styrofoam Cup- never
Aluminum Can- 200-500 years
Cotton T-shirt- 1-5 months
Apple Core- 2 months
Did any of these surprise you? no
4. What is the Great Pacific Garbage Patch? What can we do here in Iowa to help decrease it, is it even possible?
We can recycle more.
5. Define 2 Biomes of the world, define an ecosystem found in each and explain the Biotic and Abiotic factors involved.
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.
secondary consumer- snake
tertiary consumer- fox
quaternary consumer- cougar
7. What are Dead Zones in the Gulf of Mexico? What causes this situation? What can be done to help stop them?
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
Prairie dogs- the soil and water quality would drop.
Wolves- their absence would lead to prey populations rising and becoming too large.
9. Competitive Exclusion- define it and give 2 examples.
When two species compete for the same resources one will always outcompete the other causing local extinction.
Red squirrels and grey squirrels
Balanus and Chthamalus
10. Define the following terms and give 2 examples of each
Coexistence- when two species live in the same habitat but divide the resources so each can survive ()
Parasites- organism that feed off their prey but do not kill the prey or may never kill their prey (tapeworm, fleas)
Mimicry- a phenomenon through which one species has evolved to assume the appearance of another (monarch butterfly, robber fly)
Mutualism- an interaction between individuals of 2 species that is beneficial to both (oxpecker and rhino, yucca moths and yucca plants)
Commensalism- an interaction between individuals of 2 species where one species benefits and the other is neither harmed or helped (atlantic puffin and rabbits, hermit crabs)
11. Explain the Carbon Cycle and how do humans affect this cycle?
The series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
12. What is global dimming? Where does it usually affect and why is it a problem?
It affects everywhere.
It causes smog and acid rain.
13. Explain the Greenhouse Effect. How do the carbon cycle and the greenhouse effect go together?
carbon released in the air help contribute to the greenhouse effect.
14. Define endangered species and give an example. How does a species become endangered? What if this species was a keystone species? What would happen to the current ecosystem? Why should humans care about the endangered species?
Overhunting or loss of habitat.
The ecosystem would be thrown out of balance.
We would lose food sources and have more problems with pests that were previously eaten.
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?
They take up living space and displace native species.
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?
Many species would go extinct and there would be much more carbon in the atmosphere.
17. Why is human overpopulation a major concern? Explain all the resources needed for a human to sustain life.
food, water, shelter,
