What percentage of the world's land is used for agriculture?

  1. 10%

  2. 20%

  3. 30%

  4. 40%


Correct Option: C
Explanation:

Approximately 30% of the world's land is used for agriculture, including cropland, pasture, and other agricultural activities.

Which agricultural practice is known to be particularly harmful to biodiversity?

  1. Crop rotation

  2. Organic farming

  3. Monoculture

  4. Agroforestry


Correct Option: C
Explanation:

Monoculture, the practice of growing a single crop over a large area, can reduce biodiversity by eliminating the habitat and food sources of many species.

What is the term for the loss of genetic diversity in crops and livestock?

  1. Genetic erosion

  2. Biodiversity loss

  3. Habitat destruction

  4. Pollution


Correct Option: A
Explanation:

Genetic erosion refers to the loss of genetic diversity in crops and livestock due to factors such as the replacement of traditional varieties with modern hybrids and the loss of natural habitats.

Which type of agriculture is designed to minimize the negative impacts on biodiversity?

  1. Conventional agriculture

  2. Organic agriculture

  3. Permaculture

  4. Aquaculture


Correct Option: B
Explanation:

Organic agriculture is a farming system that emphasizes the use of natural methods and materials to minimize the negative impacts on biodiversity, such as the use of pesticides and fertilizers.

What is the role of biodiversity in agriculture?

  1. It provides natural pest control.

  2. It improves soil fertility.

  3. It increases crop yields.

  4. All of the above


Correct Option: D
Explanation:

Biodiversity plays a crucial role in agriculture by providing natural pest control, improving soil fertility, increasing crop yields, and supporting ecosystem services such as pollination.

Which agricultural practice can help to conserve soil biodiversity?

  1. No-till farming

  2. Contour plowing

  3. Crop rotation

  4. All of the above


Correct Option: D
Explanation:

No-till farming, contour plowing, and crop rotation are all agricultural practices that can help to conserve soil biodiversity by reducing soil erosion, improving soil structure, and increasing organic matter content.

What is the term for the process of converting natural ecosystems into agricultural land?

  1. Deforestation

  2. Land conversion

  3. Habitat destruction

  4. All of the above


Correct Option: D
Explanation:

Deforestation, land conversion, and habitat destruction are all terms used to describe the process of converting natural ecosystems into agricultural land.

Which agricultural practice can help to reduce greenhouse gas emissions?

  1. Using synthetic fertilizers

  2. Raising livestock

  3. Planting cover crops

  4. All of the above


Correct Option: C
Explanation:

Planting cover crops can help to reduce greenhouse gas emissions by capturing carbon dioxide from the atmosphere and storing it in the soil.

What is the term for the practice of managing agricultural landscapes to promote biodiversity?

  1. Agroforestry

  2. Silvopasture

  3. Permaculture

  4. All of the above


Correct Option: D
Explanation:

Agroforestry, silvopasture, and permaculture are all terms used to describe the practice of managing agricultural landscapes to promote biodiversity.

Which agricultural practice can help to improve water quality?

  1. Using drip irrigation

  2. Planting buffer strips

  3. Reducing tillage

  4. All of the above


Correct Option: D
Explanation:

Using drip irrigation, planting buffer strips, and reducing tillage can all help to improve water quality by reducing soil erosion, nutrient runoff, and pesticide contamination.

What is the term for the practice of using natural enemies to control pests in agriculture?

  1. Biological control

  2. Integrated pest management

  3. Organic farming

  4. All of the above


Correct Option: A
Explanation:

Biological control is the practice of using natural enemies, such as predators, parasites, and pathogens, to control pests in agriculture.

Which agricultural practice can help to reduce soil erosion?

  1. Contour plowing

  2. Terracing

  3. Planting cover crops

  4. All of the above


Correct Option: D
Explanation:

Contour plowing, terracing, and planting cover crops can all help to reduce soil erosion by slowing down the flow of water and trapping soil particles.

What is the term for the practice of rotating crops to improve soil fertility and reduce pests and diseases?

  1. Crop rotation

  2. Intercropping

  3. Agroforestry

  4. All of the above


Correct Option: A
Explanation:

Crop rotation is the practice of rotating crops to improve soil fertility and reduce pests and diseases.

Which agricultural practice can help to increase soil organic matter?

  1. Using compost

  2. Planting cover crops

  3. Reducing tillage

  4. All of the above


Correct Option: D
Explanation:

Using compost, planting cover crops, and reducing tillage can all help to increase soil organic matter, which is essential for soil health and fertility.

What is the term for the practice of managing agricultural landscapes to mimic natural ecosystems?

  1. Permaculture

  2. Agroforestry

  3. Silvopasture

  4. All of the above


Correct Option: A
Explanation:

Permaculture is the practice of managing agricultural landscapes to mimic natural ecosystems, with a focus on sustainability and resilience.
