Question
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.

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…
Question 4. Why nature derived carbons are good materials as com-
pared to biochar? Write the main biological precursors for na-
ture derived carbons, and describe the preparation of nature de-
rived carbons from plant derived precursors (Corn straws waste).
