David is visiting a large animal farm where many animals are kept in a small area. Which of the following would be an environmental impact of this high density animal farming?

• bad smells

• livestock can escape

• water pollution due to runoff

• improvement of feeding efficiency

Answer explanation

High density animal farming can lead to water pollution due to runoff, as waste and chemicals can contaminate nearby water sources. This is a significant environmental impact, unlike bad smells or livestock escaping.

William is a marine biologist who has noticed that global fisheries have dramatically seen a reduction in fish numbers. To help supplement that loss, he recommends a particular technique. Which technique is William most likely suggesting?

• monocropping

• IPM

• contour farming

• aquaculture

Answer explanation

Aquaculture is the farming of fish and other aquatic organisms, used to supplement declining global fish stocks. This technique helps address the reduction in fish numbers in global fisheries.

Jackson is attending a community meeting about the effects of suburban sprawl in his town. The group discusses several issues caused by suburban expansion. Which of the following is NOT a problem with suburban sprawl?

• destruction of habitats

• loss of wetlands

• noise pollution

• air and water pollution

Answer explanation

Noise pollution is not a direct consequence of suburban sprawl like habitat destruction, loss of wetlands, or air and water pollution, which are more significant environmental impacts associated with this phenomenon.

Grace has been over-irrigating her vegetable garden, and now the roots of her plants are saturated with water, causing them to die. What is this condition called?

• salinization

• desertification

• agroforestry

• waterlogging

Answer explanation

When roots are saturated with water from over-irrigation, it leads to a lack of oxygen, causing root death. This condition is known as waterlogging, making it the correct answer.

William works for a company that removes rock and other substances from the earth to sell them for profit. What is this process called?

• smelting

• mining

• urban farming

• forestry

Answer explanation

Mia is a farmer who is considering using genetically modified organisms (GMOs) for her crops. She learns that one of the advantages to using GMOs is

• reduce the need for pesticides

• they are not regulated by the government

• the concern about safety to consume

• they can cause food allergies

Answer explanation

One of the advantages of GMOs is that they can be engineered to be more resistant to pests, which reduces the need for chemical pesticides. This can lead to lower environmental impact and safer food production.

Abigail manages a farm where she uses irrigation to water her crops. Over time, she notices that as the irrigation water evaporates, salts are left behind on the soil surface. This accumulation of salts can cause plant death or lead to

• soil salinization

• desertification

• waterlogging

• monocropping

Answer explanation

When irrigation water evaporates, it leaves behind salts that accumulate in the soil, leading to soil salinization. This process can harm plant health and reduce agricultural productivity.

Aria is studying a forest ecosystem and learns that certain events can help seeds to germinate. Which of the following is a natural part of a forest ecosystem and may be required for seed germination?

• floods

• tornadoes

• fire

• polar vortex

Answer explanation

Fire is a natural part of many forest ecosystems and is essential for the germination of certain seeds, as it can clear the ground and provide the necessary conditions for growth.

Maya manages a large farm and notices that the pests attacking her crops are becoming harder to control. She finds that she has to increase the concentration of the method she uses because the pests develop resistance over time. Which method is Maya most likely using?

• GMOs

• Pestsides

• plant removal

• control burning

Answer explanation

Pesticides often require increased concentrations due to pests developing resistance over time. This makes pesticides the correct choice, as they are specifically designed to control pest populations.

Emma is studying the history of agriculture in her class. She learns about a period when crop yields dramatically increased in developing countries due to new farming techniques and technologies. What is this period called?

• a dramatic increase in crop yields in developing countries

• change to more sustainable agriculture

• way of fighting soil erosion

• power grab by the Green party in the 1980s

Answer explanation

The Green Revolution refers to the significant increase in agricultural production, particularly in developing countries, due to the introduction of high-yielding varieties, fertilizers, and irrigation techniques.
