Which of the following statements best describes the methodology used by the Colorado State University (CSU) research team to determine the impact of earthworms on global food production?
- They surveyed earthworm populations, soil properties, and crop yields from around the world, focusing on major grains and legumes to estimate earthworms' impact. (correct)
- They conducted controlled experiments in a laboratory setting, manipulating earthworm populations and measuring the resulting crop yields under precise conditions.
- They used remote sensing technology to analyze soil composition and vegetation density on a global scale, correlating these factors with earthworm habitats to infer their impact on crop production.
- They developed a complex statistical model based on historical agricultural data and climate patterns, then used this model to predict the contribution of earthworms.
Based on the information provided, what is the most likely reason that earthworms have a more significant impact on crop yields in Sub-Saharan Africa and Latin America compared to other regions?
Based on the information provided, what is the most likely reason that earthworms have a more significant impact on crop yields in Sub-Saharan Africa and Latin America compared to other regions?
- The climate and soil conditions in Sub-Saharan Africa and Latin America are uniquely suited to support large earthworm populations, leading to increased soil turnover and nutrient availability.
- Farmers in these regions may have limited access to chemical fertilizers and pesticides, making them more reliant on the benefits of earthworm-rich organic matter for crop production. (correct)
- The species of earthworms found in these regions are genetically superior at enhancing soil fertility and plant growth compared to earthworms in other parts of the world.
- Farmers in these regions have traditionally employed advanced soil management techniques that synergize with the presence of earthworms to maximize crop production.
In what way do earthworms enhance soil structure to improve plant growth, according to the research?
In what way do earthworms enhance soil structure to improve plant growth, according to the research?
- Earthworms compact the soil, which prevents erosion and provides a stable base for plant roots to anchor themselves.
- Earthworms consume decaying plant matter on the surface, preventing the buildup of harmful substances that can inhibit plant growth.
- Earthworms secrete a special enzyme that directly stimulates root growth, leading to stronger and more productive plants.
- Earthworms create channels that loosen and aerate the soil, which allows water to drain and be stored, and their movement churns organic matter, making nutrients available to plants. (correct)

Study Notes
- Earthworms enrich soil, boost crop yields, and protect plants from microplastics.
Crop Yields Boost
- Earthworms are responsible for 6.5 percent of global food production annually.
- This is the equivalent of 140 million tons.
- This amount is comparable to Russia's annual grain harvest.
- Earthworms increased grain yields by 10 percent in Sub-Saharan Africa.
- Earthworms increased grain yields by 8 percent in Latin America.
- Farmers in developing countries may be more reliant on earthworms due to a lack of access to fertilizers and pesticides.
How Earthworms Help
- Burrowing creates channels that loosen and aerate the soil.
- This allows water to drain and be stored underground.
- The earthworms' movement helps churn the soil, making nutrients more available to plants.
Protection From Microplastics
- Tomato plants in soil contaminated with plastic particles thrived when earthworms were present.
- Earthworms help boost the tomato plants’ immune systems.
- This makes them more resilient to environmental changes and helps them repel bugs.
