  2. Promoting biodiversity and ecological balance

  3. Genetically modifying crops

  4. Intensive monoculture

Show answer
Correct Option: B
Explanation:

Organic farming emphasizes maintaining a balanced ecosystem by promoting biodiversity, reducing the use of synthetic inputs, and enhancing soil health.

How does organic farming contribute to soil health?

  1. By using synthetic fertilizers to increase soil fertility

  2. By incorporating crop residues and organic matter to improve soil structure

  3. By applying chemical pesticides to control pests and diseases

  4. By using genetically modified crops to resist pests and diseases

Show answer
Correct Option: B
Explanation:

Organic farming practices, such as crop rotation, cover cropping, and composting, help to improve soil structure, increase organic matter content, and enhance soil biodiversity.

Which of the following is a potential environmental benefit of organic farming?

  1. Increased water pollution due to excessive fertilizer use

  2. Reduced biodiversity due to monoculture farming

  3. Enhanced soil erosion due to lack of synthetic pesticides

  4. Reduced greenhouse gas emissions and improved carbon sequestration

Show answer
Correct Option: D
Explanation:

Organic farming practices, such as reduced tillage, cover cropping, and composting, can help to mitigate climate change by reducing greenhouse gas emissions and enhancing carbon sequestration in the soil.

How does organic farming promote biodiversity?

  1. By using genetically modified crops that are resistant to pests and diseases

  2. By relying on synthetic pesticides and fertilizers to control pests and diseases

  3. By encouraging crop rotation and the use of diverse cover crops

  4. By practicing intensive monoculture farming

Show answer
Correct Option: C
Explanation:

Organic farming practices, such as crop rotation, cover cropping, and the use of diverse crop varieties, help to promote biodiversity by creating a more balanced and resilient ecosystem.

Which of the following is a challenge associated with organic farming?

  1. Increased yields due to the use of synthetic fertilizers

  2. Reduced pest and disease pressure due to the use of chemical pesticides

  3. Higher production costs compared to conventional farming

  4. Improved soil health due to the use of organic matter

Show answer
Correct Option: C
Explanation:

Organic farming practices, such as reduced synthetic input use and labor-intensive methods, can lead to higher production costs compared to conventional farming.

How does organic farming contribute to sustainable agriculture?

  1. By using genetically modified crops to increase yields

  2. By relying on synthetic pesticides and fertilizers to control pests and diseases

  3. By promoting soil health, biodiversity, and ecosystem balance

  4. By practicing intensive monoculture farming

Show answer
Correct Option: C
Explanation:

Organic farming practices aim to promote soil health, biodiversity, and ecosystem balance, which are key elements of sustainable agriculture.

Which of the following is a potential environmental impact of conventional farming?

  1. Reduced water pollution due to efficient irrigation practices

  2. Enhanced soil health due to the use of synthetic fertilizers

  3. Increased biodiversity due to the use of diverse crop varieties

  4. Increased greenhouse gas emissions and water pollution due to excessive fertilizer use

Show answer
Correct Option: D
Explanation:

Conventional farming practices, such as the excessive use of synthetic fertilizers and pesticides, can lead to increased greenhouse gas emissions, water pollution, and soil degradation.

How does organic farming contribute to food security?

  1. By using genetically modified crops to increase yields

  2. By relying on synthetic pesticides and fertilizers to control pests and diseases

  3. By promoting sustainable farming practices that enhance soil health and biodiversity

  4. By practicing intensive monoculture farming

Show answer
Correct Option: C
Explanation:

Organic farming practices, by promoting sustainable farming practices that enhance soil health and biodiversity, can contribute to food security by increasing crop yields and resilience to environmental stresses.

Which of the following is a potential economic benefit of organic farming?

  1. Reduced production costs due to the use of synthetic inputs

  2. Increased market demand for organic products

  3. Lower yields compared to conventional farming

  4. Increased reliance on government subsidies

Show answer
Correct Option: B
Explanation:

Organic farming can benefit farmers economically due to the increased market demand for organic products, which often command higher prices.

How does organic farming contribute to climate change mitigation?

  1. By using synthetic fertilizers to increase soil carbon content

  2. By relying on chemical pesticides to control pests and diseases

  3. By promoting soil health and carbon sequestration through organic matter management

  4. By practicing intensive monoculture farming

Show answer
Correct Option: C
Explanation:

Organic farming practices, such as cover cropping, composting, and reduced tillage, help to promote soil health and carbon sequestration, which contribute to climate change mitigation.

Which of the following is a potential challenge associated with the transition to organic farming?

  1. Increased yields due to the use of synthetic fertilizers

  2. Reduced pest and disease pressure due to the use of chemical pesticides

  3. Higher production costs during the transition period

  4. Improved soil health due to the use of organic matter

Show answer
Correct Option: C
Explanation:

The transition to organic farming may involve higher production costs during the initial years due to the need for investment in organic inputs, infrastructure, and training.

How does organic farming contribute to water quality protection?

  1. By using synthetic fertilizers to increase crop yields

  2. By relying on chemical pesticides to control pests and diseases

  3. By reducing the risk of water contamination from synthetic inputs

  4. By practicing intensive monoculture farming

Show answer
Correct Option: C
Explanation:

Organic farming practices, by reducing the use of synthetic fertilizers and pesticides, help to minimize the risk of water contamination from agricultural runoff.

Which of the following is a potential social benefit of organic farming?

  1. Increased unemployment due to reduced labor requirements

  2. Improved working conditions for farmworkers due to reduced exposure to synthetic chemicals

  3. Increased reliance on government subsidies

  4. Reduced access to affordable food for consumers

Show answer
Correct Option: B
Explanation:

Organic farming practices, by reducing the use of synthetic chemicals, can improve working conditions for farmworkers by reducing their exposure to potentially harmful substances.

How does organic farming contribute to the preservation of traditional farming knowledge and practices?

  1. By relying on genetically modified crops and modern technologies

  2. By promoting the use of synthetic fertilizers and pesticides

  3. By encouraging the adoption of traditional farming methods and crop varieties

  4. By practicing intensive monoculture farming

Show answer
Correct Option: C
Explanation:

Organic farming practices often involve the adoption of traditional farming methods and crop varieties, which helps to preserve traditional farming knowledge and practices.

Which of the following is a potential limitation of organic farming?

  1. Increased yields due to the use of synthetic fertilizers
