Questions and Answers
- 1.
What is an ecosystem?
- A.
It is a video game that I can play online.
- B.
It is a place having unique physical features--including air, water, and land--supporting plant and animal life.
- C.
It is a body system that breaks down the vegetables I eat.
Correct Answer
B. It is a place having unique physical features--including air, water, and land--supporting plant and animal life.Explanation
An ecosystem is a natural unit consisting of all plants, animals and micro-organisms (biotic factors) in an area functioning together with all of the non-living physical (abiotic) factors of the environment. An ecosystem is a completely independent unit of interdependent organisms which share the same habitat. Ecosystems usually form a number of food webs which show the interdependence of the organisms within the ecosystem.Rate this question:

What is the symbol for recycling?
- A.
A pine tree.
- B.
Three arrows that create an endless loop.
- C.
Five golden rings.
Correct Answer
B. Three arrows that create an endless loop.Explanation
Recycling involves processing used materials into new products in order to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to virgin production.[1][2] Recycling is a key component of modern waste management and is the third component of the "Reduce, Reuse, Recycle" waste hierarchy.Rate this question:

How does planting trees help our environment?
- A.
Clean the air.
- B.
Provide homes for birds and other animals.
- C.
Trees help reduce pollution in the air.
- D.
All of the above.
Correct Answer
D. All of the above.Explanation
Trees are an important component of the natural landscape because of their prevention of erosion and the provision of a weather-sheltered ecosystem in and under their foliage. Trees also play an important role in producing oxygen and reducing carbon dioxide in the atmosphere, as well as moderating ground temperatures. They are also elements in landscaping and agriculture, both for their aesthetic appeal and their orchard crops (such as apples).Rate this question:

What is a carbon footprint?
- A.
A dinosaur fossil.
- B.
A measure of the impact our actions and daily activities have on our planet and the climate.
- C.
A cute picture you made with your feet to give to mom.
Correct Answer
B. A measure of the impact our actions and daily activities have on our planet and the climate.Explanation
A carbon footprint is “the total set of GHG (greenhouse gas) emissions caused directly and indirectly by an individual, organization, event or product” (UK Carbon Trust 2008). An individual, nation or organization's carbon footprint is measured by undertaking a GHG emissions assessment. Once the size of a carbon footprint is known, a strategy can be devised to reduce it.
Carbon offsets, or the mitigation of carbon emissions through the development of alternative projects such as solar or wind energy or reforestation, represent one way of managing a carbon footprint.
The concept and name of the carbon footprint originates from the ecological footprint discussion.[1] The carbon footprint is a subset of the ecological footprint.Rate this question:

What is composting?
- A.
Posting info about the environment online.
- B.
Pulling weeds in your garden.
- C.
Recycling scraps of fruit, vegetables, and other organic materials by planting them outside.
Correct Answer
C. Recycling scraps of fruit, vegetables, and other organic materials by planting them outside.Explanation
Composting upcycles organic kitchen and yard waste and manures into an extremely useful humus-like, soil end product, permitting the return of vital organic matter, nutrients, and particularly bacteria, that are vital to plant nutrition to the soil. Managed aerobic composting arranges environmental conditions so they are optimal for the natural processes to take place. There is a popular expression: "compost happens", but it is helpful to engineer the best possible circumstances for large amounts of organic waste to decompose quickly and efficiently, with the greatest conservation of useful nutrients and mass.Rate this question:

What is the greenhouse effect?
- A.
When your mom decides to paint your house green one summer.
- B.
When the weather gets warmer and plants start growning in the Spring.
- C.
The rise in temperature the Earth experiences because certain gases in the atmosphere trap energy from the sun to warm up the Earth.
Correct Answer
C. The rise in temperature the Earth experiences because certain gases in the atmosphere trap energy from the sun to warm up the Earth.Explanation
The greenhouse effect refers to the change in the steady state temperature of a planet or moon by the presence of an atmosphere containing gas that absorbs and emits infrared radiation.[1] Greenhouse gases, which include water vapor, carbon dioxide and methane, warm the atmosphere by efficiently absorbing thermal infrared radiation emitted by the Earth’s surface, by the atmosphere itself, and by clouds. As a result of its warmth, the atmosphere also radiates thermal infrared in all directions, including downward to the Earth’s surface. Thus, greenhouse gases trap heat within the surface-troposphere systemRate this question:

What does it mean when food is organic?
- A.
It is food that is made or grown without the use of chemicals or pesticides.
- B.
It won't taste good.
- C.
It was made while someone was playing the organ.
Correct Answer
A. It is food that is made or grown without the use of chemicals or pesticides.Explanation
Organic foods are made according to certain production standards. The use of conventional non-organic pesticides, insecticides and herbicides is greatly restricted and avoided as a last resort. However, contrary to popular belief, certain non-organic fertilisers are still used. If livestock are involved, they must be reared without the routine use of antibiotics and without the use of growth hormones, and generally fed a healthy diet. In most countries, organic produce may not be genetically modified.Some studies have shown higher nutrient levels in organic fruit and vegetables compared with conventionally grown products.[53].
The most important study of organic food to date was completed in 2007[54] and found that organic fruit and vegetables contain up to 40% more antioxidants than conventional equivalents, and that the figure was 60% for organic milk.Rate this question:

Which of these things is something you could do to save our planet?
- A.
Turn off the water while your brush your teeth.
- B.
Ride your bike or walking to school.
- C.
Remind your parents to bring reusable bags when you go grocery shopping.
- D.
All of the above.
Correct Answer
D. All of the above.Explanation
Water conservation refers to reducing the use of water we use to save energy.
Riding your bike reduces pollution and greenhouse gas emissions from needing a car ride.
A reusable shopping bag, sometimes called bag for life is a type of shopping bag which can be reused several or even many times: this is an alternative of single use paper or plastic bags. It is often made from fabric such as canvas, or sometimes thick plastic. It is more durable than disposable plastic bags, allowing multiple use.
Reusable shopping bag is a kind of carrier bags, which is available for sale in supermarkets and apparel shops. Reusable shopping bag requires less waste of [natural resources such as oil and less emission of carbon dioxide to produce than plastic bags. In some countries, production and distribution of single-use plastic bags are regulated by law in.Rate this question:
