Chapter 6, Problem 1DAA
Summary Introduction
To determine: How much energy did the ethanol produced from one hectare of corn yield and how much energy did it took to grow the corn.
Concept introduction: The plants and other organic material, other than fossils, can also be used as a source of energy. The oils, gases, and alcohols made from these materials are called biofuels. The crops such as corn and others that are rich in oils, starch, and sugars can easily be transformed into biofuels.

On a maize farm in Ethiopia, the insolation energy is 5,654,875 calories/m^2/day. The gross productivity of the rice is 0.02742g/cm^2/day, and 35% of the energy is lost due to respiration. There are 4000 calories in 1 gram of maize. Calculate the net primary productivity of the maize and the efficiency of photosynthesis of maize. Show work below.

Matching Type. Match column A with the correct answer in column B. Write only the letter of
correct answer on a separate sheet of paper.
COLUMN A
1. This is the cultivation of a single crop in large areas.
Vast tracts of land are converted to rice farms, sugar farms, and
coconut farms.
2. This is used by farmers to kill insect pests and weeds.
3. The continuous and uncontrolled use of this product may
increase soil acidity, thus destroying soil structure.
4. This can include clearing the land for agriculture or
grazing, or using the timber for fuel, construction, or
manufacturing.
5. Farmers use plastic sheets as mulch to cover 50-70%
of the soil and allow them to use drip irrigation systems to have
better control over soil nutrients and moisture.
6. A huge amount of agricultural territory is used primarily
as pasture for cattle and other livestock.
7. Antimicrobial resistant bacteria can move from farms to
humans through food and airborne dust.
_8. It is a…

- Azlina wanted to maximize the bio-char yield in her experiment so that she can utilize the biochar in the subsequent pot trials to improve the crop yield. She decided to run a torrefaction reaction on biomass at a moderate temperature of 240 oC whereby the biochar yield was 20 wt%. Later on, she found out that biochar can be produced by pyrolysis with a higher yield of 40 wt% but operating at a higher temperature of 500 oC. The amount of biochar yield almost doubled from her yield from the torrefaction process. Explain whether any error involved in her experiment, then describe the error involved and suggest the method to improve the biochar yield.arrow_forwardPlease write clearlyarrow_forwardEthanol can be produced either from plant biomass using microbial fermentation or from ethylene using chemical synthesis way.

- Question 1 Which of the following statements describes the semi-dwarf wheat varieties developed in the Green Revolution? Their harvest is easier with heavy machinery. O They were bred for lodging sensitivity, which is an advantage in the field. As they are shorter, grain heads can touch the ground and give the plant more stability. These plants need more time to make enough carbohydrates to grow.arrow_forwardAccording to the water potential values shown in the image, which ones are wrong and why?

The leaves of the plant in front of the fan had the highest initial water potential and therefore lost the most water. The control plant had lower initial water potential in the root area and therefore lost less water. The control plant had a lower initial mass and so lost water at a decreased rate. The fan rapidly moves water molecules away from the leaf surface, lowering the water potential.arrow_forward
