Oxygen is not a greenhouse gas, while carbon dioxide, methane, and nitrous oxide are all greenhouse gases emitted by agriculture.

Livestock production is the largest contributor to methane emissions, accounting for about 65% of total methane emissions from agriculture.

Synthetic fertilizers are the primary source of nitrous oxide emissions from agriculture, accounting for about 70% of total nitrous oxide emissions from agriculture.

All of the above agricultural practices can help to reduce carbon dioxide emissions. Planting trees helps to absorb carbon dioxide from the atmosphere, using renewable energy sources reduces the need for fossil fuels, and reducing fertilizer application can help to reduce nitrous oxide emissions, which is a potent greenhouse gas.

Photosynthesis is the process by which plants remove carbon dioxide from the atmosphere and use it to produce food.

Monoculture is not a climate-smart agricultural practice because it can lead to soil erosion, water pollution, and increased greenhouse gas emissions.

All of the above terms can be used to describe the practice of managing livestock in a way that reduces greenhouse gas emissions.

There is a wealth of scientific knowledge about climate change, including its causes, impacts, and potential solutions. The challenges associated with reducing greenhouse gas emissions from agriculture are more related to the need to increase food production, the high cost of climate-smart agricultural practices, and the lack of political will to address climate change.

Respiration is the process by which soil releases carbon dioxide into the atmosphere. Respiration is carried out by microorganisms in the soil that break down organic matter.

Increased crop yields are not a potential consequence of climate change for agriculture. In fact, climate change is expected to have a negative impact on crop yields, due to factors such as increased temperatures, more frequent and severe droughts, and increased pest and disease outbreaks.

All of the above terms can be used to describe the practice of managing agricultural land in a way that conserves soil and water resources.

Increasing the use of synthetic fertilizers is not a potential solution to reducing greenhouse gas emissions from agriculture. In fact, synthetic fertilizers are a major source of nitrous oxide emissions, which is a potent greenhouse gas.

Crop rotation is the practice of growing different crops on the same land in a sequential order. Crop rotation helps to improve soil fertility, reduce pests and diseases, and control weeds.

Genetically modified crops are not a climate-smart agricultural technology. In fact, there is some evidence that genetically modified crops can actually increase greenhouse gas emissions.

All of the above terms can be used to describe the practice of managing agricultural land in a way that mimics natural ecosystems.
