The planting of trees e. All those millions and millions of flatulent insects

Explanation / Answer

Q7. a.True

Plant cells carry out photosynthesis to produce food and cellular respiration to generate energy by burning sugars.

Q8.C. Alcoholic fermentation

Q9. d glycolysis

Q10.a. Lactic acid

lactic acid fermentation occurs in the mammalian cells under anaerobic conditions (Muscle cells)

Q11. c. burning of fossil fuels

Burning of fossil fuels produce large amounts of gases such as CO2, CO which contribute for greenhouse effect.
