Which of the following is true about global food production?
A. If we continue growing crops for biofuel production and agricultural feed, we will be able to feed billions more people.
B. If we eliminated the production of grain-fed animals and maintained current yield and cropland, it is predicted that we could feed an additional 4,000 million people.
C. Although poverty is linked to hunger, food production is the major cause of hunger.
D. To increase food production, the only option is to increase the yield per area farmed.

Part D
The bar graph shows the cost per megawatt-hour comparison of various renewable and nonrenewable energy sources in
the United States. The blue portion of the bars represents the cost of electricity. The red portion represents the additional
system costs of harnessing that type of energy. Systems costs may include equipment expenses and costs of connection
to a power grid.

Of the 1000 J of energy that was in the consumed seeds, the bird stored 10 J of energy in its body, eliminated 150 J of energy in its waste, and used the remaining energy to respire. What is the production efficiency of this bird?

Considering the scenario where the number of lost owls (4) is replaced by snakes, compute for energy units following the table in no. 1 (Sun + E = 6) and answer the following questions: In comparison with the natural food chain, which component received less energy in this unbalanced food chain? What is the reason for the above? What might be the consequences of the above? What is needed to recover balance in the food chain? How can this be achieved in this specific situation?arrow_forward
- In general, the ratio of oxidized versus reduced NAD is best described by which ONE statement below? A. the NADH/NAD+ ratio is greater than 1 B. the NADH/NAD+ ratio is always changing so one cannot make generalized assertions about this ratio C. the NAD+/NADH ratio is greater than 1 D. the NAD+/NADH ratio is equal to 1arrow_forwardIs feed cost an important part in animal production? Why or why not?arrow_forwardWhich of the following statements about nutrient challenges faced by organisms is FALSE? Carnivores are limited by the ratio of carbon to nitrogen found in prey. Detritivores consume food rich in carbon but poor in nitrogen. Plants can exhibit the same type of functional response curve describing the rate of energy intake as carnivores. The diet of a carnivore can vary geographically depending on the availability of prey.arrow_forward
- Ecologyarrow_forwardBackground A trophic level, or feeding level, is made up of all the organisms whose energy source is the same number of consumption steps from the sun in a given ecosystem. The trophic level of plants or producers is 1, while that of herbivores is 2 and that of animals that eat herbivores 3. Higher trophic levels can exist for animals even higher on the food chain. In this exercise, you will compute numerical values for human energy needs based on diets at different trophic levels. In this case study the owner of a farm raises soybeans and chickens. Grasshoppers feed on the farmers soybeans, and are in turn eaten by the chickens. Humans can, though rarely do, eat grasshoppers for sustenance. Humans can also eat soybeans. For the purpose of this exercise, make the following assumptions: A human requires 1 chicken/day There are 365 days/year 1 chicken eats 25 grasshoppers/day 1 grasshopper requires about 30 g of soybeans/year 1,000 grasshoppers have a mass of 1 kg 1 human requires…arrow_forwardBackground A trophic level, or feeding level, is made up of all the organisms whose energy source is the same number of consumption steps from the sun in a given ecosystem.
