B. By using water, electricity sparingly instead of in lots of quantities.

C. I think i could if i put the time and effort into it.

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.

A. Fossil fuels, including coal, oil and natural gas, are currently the world's primary energy source. Formed from organic material over the course of millions of years, fossil fuels have fueled U.S. and global economic development over the past century.

B. Renewable energy is generally defined as energy that is collected from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.

h. 200-500 years

i. 6 months

j. 2 months

k. A tin can can go 50 years before being decomposed.

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

1. The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean.

2. Reduce your needs for plastic items.

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

1. Grassland biomes are large, rolling terrains of grasses, flowers and herbs.

2. A savanna is a rolling grassland scattered with shrubs and isolated trees, which can be found between a tropical rainforest and desert biome.

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.

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

1. Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes.

2. Caused by "excessive nutrient pollution from human activities.

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 species are species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.

An American Alligator is a Keystone Specie

Bees are Keystone Species

10. Define the following terms and give 2 examples of each a. Coexistence b. Parasites c. Mimicry d. Mutualism e. Commensalism

A. Exist at the same time or in the same place

B. Live on other organisms

C. Imitate other organisms

D. Live together

E. Association between two organisms

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?

Global dimming is defined as the decrease in the amounts of solar radiation reaching the surface of the Earth. The by-product of fossil fuels are tiny particles or pollutants which absorb solar energy and reflect back sunlight into the space.

13. Explain the Greenhouse Effect. How do the carbon cycle and the greenhouse effect go together?

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.

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?

Endangered species are species that are close to being extinct. A tiger is endangered.

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?

Invasive species are plants, animals, or pathogens that are non-native

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?

People are cutting down trees and destroying plants.

17. Why is human overpopulation a major concern? Explain all the resources needed for a human to sustain life.

There needs to be more resources and food that we don't have.

18. Pesticides- what are they, how do they adversely affect the environment, and how does this create problems with the genetic diversity in crop production.

The only toxic substances released intentionally into our environment to kill living things.

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

Bees play a huge part on Earth, cause they keep plants alive and produce more plants.

20. It is the year 2070 and you are having a conversation with your grandchildren about how the environment has changed since you were young- give a prediction of how the Earth would look to them.

It would be a desert and it would be very hot.
