Question

select the correct answer.
an area recently became prone to deforestation. now there are few trees left in the vicinity. how would this change affect the cycles of earth?
a. more carbon dioxide would be used by the plants.
b. more carbon would be available to animals for consumption.
c. less transpiration would take place.
d. less nitrogen would be needed by animals.

Explanation:

• Option A: With fewer trees (plants), less carbon dioxide will be used by plants (as photosynthesis which uses CO₂ is reduced), so this option is incorrect.
• Option B: Deforestation doesn't directly lead to more carbon available for animal consumption. Carbon in plants (as a food source for some animals) is reduced due to fewer trees, so this option is incorrect.
• Option C: Transpiration is the process by which water is evaporated from plant leaves. Fewer trees mean less transpiration. This is correct.
• Option D: Nitrogen needs of animals are not directly related to deforestation in the way described. Nitrogen cycle is more related to soil bacteria, decomposition etc. and not directly to tree - number reduction in this context, so this option is incorrect.

Answer:

C. Less transpiration would take place.
