Environmental Science Concepts

Explain how our population has changed over time.

• The global population has increased significantly due to advances in medicine, agriculture, and sanitation.

• The global population has remained stable with little change over the years.

• The global population has decreased due to natural disasters and wars.

Where is most of the earth’s freshwater found?

• In rivers and lakes

• In the atmosphere

• In glaciers and ice caps

What is sustainability? Are we living sustainably? Why or Why not?

• Sustainability is the ability to meet present needs without compromising future generations.

• Sustainability means using resources as quickly as possible.

• Sustainability is about maximizing profit for businesses.

Describe how food production and agriculture has changed over time.

• Food production has remained the same throughout history.

• Food production has shifted from subsistence farming to industrial agriculture with increased use of technology and chemicals.

• Agriculture has become less efficient due to traditional practices.

• Food production is now solely dependent on organic farming methods.

What is the difference between producers and consumers?

• Producers create their own food through photosynthesis, while consumers obtain energy by eating other organisms.

• Producers are animals that eat plants, while consumers are plants that create food.

• Producers and consumers are both types of animals that eat each other.

• Producers are organisms that do not require energy, while consumers are those that do.

How can someone help reduce carbon emissions?

• By using public transportation, reducing energy consumption, and supporting renewable energy sources.

• By increasing the use of fossil fuels and driving more frequently.

• By ignoring energy-saving practices and using more electricity.

• By promoting deforestation and industrial waste.

Diagram an energy pyramid and label the different levels.

• Producers at the base, followed by Primary Consumers, Secondary Consumers, and Tertiary Consumers at the top.

• Primary Consumers at the base, followed by Producers, Secondary Consumers, and Tertiary Consumers at the top.

• Tertiary Consumers at the base, followed by Secondary Consumers, Primary Consumers, and Producers at the top.

• Secondary Consumers at the base, followed by Tertiary Consumers, Producers, and Primary Consumers at the top.

• Grass, Grasshopper, Frog, Snake, Hawk, Tree, Deer, Rabbit, Fox, and Owl.

• Grass, Ant, Lizard, Eagle, Shrub, Mouse, Bear, Fish, Toad, and Squirrel.

• Corn, Caterpillar, Tortoise, Owl, Pine Tree, Rabbit, Wolf, Deer, Spider, and Hawk.

• Wheat, Beetle, Snake, Crow, Maple Tree, Antelope, Fox, Frog, Shark, and Eagle.

How are private and public land managed differently?

• Private land is managed by individuals or organizations for personal use, while public land is managed by government agencies for public benefit.

• Private land is managed by government agencies, while public land is managed by individuals for personal use.

• Both private and public land are managed by government agencies for public benefit.

• Private land is managed collectively by communities, while public land is owned by individuals.

What are some of the major contributors to food waste?

• Overproduction, poor storage, and consumer behavior.

• Increased demand for organic food.

• Strict food safety regulations.

• High prices of food products.
