Question

Environmentalists are monitoring an area of tropical forest. They made the following graph to predict the effect of deforestation on this area over the next 20 years.

What would a graph of oxygen production look like for this forested area?

A. A line that is leveling out

B. A line that is decreasing

C. A line that is slowly rising

D. A line that is increasing

Answer 1

B. a line that is decreasing.
if tress are disappearing then oxygen levels would decrease as well since trees give us oxygen and we give them carbon dioxide.

Answer 2

The correct answer is option B

By seeing the graph we can easily say that we see a graph that is decreasing. We can predict that in the next 20 years the number of trees will be be reduced in number.

Due to decrease in the number of trees, the oxygen concentration will also decrease. The production of oxygen will decrease for sure as trees are main source of production of oxygen in the rainforest.
