The term "agricultural commodity" typically refers to any raw material or primary product that is derived from agriculture, and beef cattle fits this definition as it is a primary product of the agricultural industry.

Light, air, water, and soil are all essential for plant growth. Light is needed for photosynthesis, the process by which plants convert sunlight into energy. Air provides carbon dioxide, which is also necessary for photosynthesis. Water is essential for transporting nutrients and minerals throughout the plant and for maintaining turgidity. Soil provides the necessary nutrients and minerals that plants need to grow and thrive. Therefore, all four options are needed for plant growth.

The industry that saw consumption peak in the 1970s was the beef industry. This means that during that time, people were consuming more beef compared to other meats like poultry, pork, and lamb.

Insects can damage a plant by eating it and spreading plant diseases. When insects feed on plants, they can cause physical damage to the leaves, stems, and roots, which can weaken the plant and make it more susceptible to diseases. Additionally, some insects act as carriers for plant diseases, spreading them from one plant to another as they move and feed. This can lead to the rapid spread of diseases, causing further damage to the plant and potentially leading to its death. Therefore, both eating the plant and spreading diseases are ways in which insects can harm plants.

Of each dollar you spend on food, 19% of it goes to the farmer. This means that out of the total amount you spend on food, 19% of that amount is given to the farmers who produce the food. The rest of the options, such as the processor and packager, the trucker, and the wholesaler and marketer, do play a role in the food supply chain, but the question specifically asks about the percentage that goes to the farmer.

A GMO refers to a Genetically Modified Organism, which is an organism whose genetic material has been altered using genetic engineering techniques. This alteration is done to introduce specific traits or characteristics into the organism that are not naturally occurring. The term "Genetically Made Organic" and "Genetically Manufactured Organic" are not commonly used or recognized terms in the context of GMOs. "Generic Modified Organism" is a combination of words that do not accurately describe the concept of GMOs.

The phrase "the beast. I mean, best." is a play on words, using a pun to create a humorous effect. The word "beast" is used sarcastically to imply that Mr. Cochran's class is challenging or difficult, while the word "best" is used to convey that the class is actually excellent or superior. This answer suggests that Mr. Cochran's class is not only the best, but it is also demanding and requires a lot of effort from the students.

The correct answer explains that genetic modification is done in a lab, while selective breeding is done in a greenhouse.

Branding, castrating, and dehorning are management practices used to produce meat. These practices are commonly performed on farm animals to ensure their safety, improve handling, and maintain the quality of meat. Branding helps identify ownership and prevent theft, castrating reduces aggression and improves meat quality, and dehorning prevents injuries to both animals and humans. While these practices may vary in legality and regulation across states, they are generally accepted and widely practiced in the meat production industry.

The correct answer is "all the above." This is because both frost resistant strawberries and Bt "caterpillar killing" corn are examples of genetically modified organisms (GMOs). Genetically modified organisms are organisms whose genetic material has been altered using genetic engineering techniques. In the case of frost resistant strawberries, genes from other organisms are inserted into the strawberry's DNA to make it more resistant to frost. Similarly, Bt "caterpillar killing" corn has been genetically modified to produce a toxin that kills certain pests. Therefore, both examples given in the question are valid examples of GMOs.

Plant science is the study of plants, including their growth, development, and interactions with the environment. It encompasses various aspects such as production, research, biotechnology, and the development of hybrid plants.

Using ladybug beetles to eat aphids instead of spraying pesticides is an example of a production agriculturist practicing environmental stewardship because it demonstrates a commitment to natural pest control methods. By relying on ladybug beetles, the agriculturist avoids the use of harmful pesticides that can negatively impact the environment and other beneficial organisms. This approach promotes a healthier ecosystem and reduces the potential harm to non-target species.

Precision Farming technology involves using advanced tools and techniques to optimize agricultural practices. The use of GPS systems to apply fertilizer to crop fields is an example of precision farming. By using GPS technology, farmers can accurately determine the precise areas that require fertilization, ensuring that the fertilizer is applied in the right amount and at the right location. This helps to minimize waste, reduce environmental impact, and improve crop yield and quality.

Brazil is not a chief importer of U.S. agricultural goods. This means that Brazil does not play a significant role in importing agricultural goods from the United States.

Free roaming chickens in an open barnyard can be considered farm animal abuse because they are exposed to potential dangers, such as predators or extreme weather conditions. They may not have access to proper shelter, food, or water, and their overall welfare may be compromised. On the other hand, egg laying hens kept in stacked cages, while not ideal, may still receive basic necessities and protection from external threats. Feeding antibiotics to chickens can be a common practice to prevent and treat diseases, ensuring their health. Branding, although painful, is often done under controlled conditions and is necessary for identification purposes.

On average, Americans spend 10 percent of their disposable income on food. This indicates that food expenses make up a significant portion of their budget.
