- After measuring mass, energy content, and dollar value for each food type, the researchers calculated emissions per kilogram, calorie, and dollar. In every case, red meat produced the most emissions, followed by dairy products and chicken, fish, and eggs. They then calculated that shifting one’s diet from meat and dairy to fruits, vegetables, and grains for just one day per week would reduce emissions as much as eating 100% locally (cutting food-miles to zero) all the time. Knowing all this, how would you choose to reduce your own food footprint? By how much do you think you could reduce itDiscuss how value addition by the production of products from processing wastes/byproducts addresses food security and poverty alleviation.Why is there a need to study about the conversion of waste to value added products? What is its significance to the people and the environment? Please justify.
- There are wastes of four fruits peels; apple, orange, banana, and pineapple were used for this experiment. The percentage of biomass produced and moisture content were calculated by using the given formulas. It is given that the weight of each substrate is equal to 40 grams. The biomass produced is maximum in apple peel followed by banana peel, orange peel, and pineapple peel ( observation 1) and banana peel has highest moisture content followed by orange peel, pineapple peel, and apple peel (observation 2). QUESTION: Please give the clear explanation for both observations and justify your answer.Can you explain the last part of the consumption of berries? I know the fourth level is 0.01% and 100kg biomass but I am not getting those answers. thanksAccording to Damron, aquaculture accounts for what percentage of total US cash receipts of total animal agriculture? 0.3 0.85 1.5 2.5 5
- If 100,000 kJ of energy is available to the producers, how much energy is available to the secondary consumers in a food pyramid.Nutrients (such as N, P. K) are important for the increase in net primary production which will be used by the consumers for growth and reproduction. In an aquaculture pond, why is it disadvantageous to exceed the saturation levels of fish feed (proteins, lipids, carbohydrates, vitamins) for the growth of aquaculture fishes. What are effects of this activity in the aquatic environment and organisms. Discuss in light of the lecture made earlier about productivity and nutrient cycling?How has food policy in the U.S. impacted the production of your food item? What are some specific consequences to various stakeholders, meaning companies, farmers, or anyone with some vested interest in the production and distribution of the product? Has the most recent policy, the 2018 Farm Bill, helped or hindered? Has it had opposing influences on stakeholders? (With references)
- Which of the following statements is correct? For this question 1 or more statements may be correct. If you select an incorrect statement you will lose points. When it comes to measuring the productivity of farms over the years USDA does not prefer looking at the crop yield per acre and the agricultural value-added per worker Productivity measures changes in the efficiency with which inputs are transformed into outputs The 3 special conditions of agriculture mentioned in the lectures are: biological, physical and market conditions Asset fixity is a problem because it is difficult to purchase the required capital equipment for farms Functional foods, are Foods designed to have only basic nutritional functions.Since the US has blended more and more ethanol into its gasoline, US production of ethanol has increased through your lifetime, and the data in the chart below basically show this. But production of ethanol in the US dropped slightly in the year Annual World Fuel Ethanol Production (Mil.
