This is an example of thigmotropism I believe.
Answer:
Option (D)
Explanation:
The tropical rain forest and tropical dry forest lies on the tropical regions of both the hemisphere. These are the regions on and around the tropic of cancer and tropic of capricorn. In the tropical rain forest, the rate of precipitation is higher than the rate of evapo-transpiration, so the temperature remains relatively cooler. Whereas, in the tropical dry forest, the rate of evapo-transpiration is more than the rate of precipitation, as a result of which the temperature remains comparatively high.
The tropical dry forest is very good for agricultural purpose, as it contains nutrient rich soil. So it has been destroyed to a greater extent for agricultural use, grazing of animals.
Whereas, the tropical rain forest is not suitable for the agricultural use because the soil here are affected by the rainfall, that washes away the nutrients, making the soil less fertile.
Thus the correct answer is option (D).
ATP means adenine tri-phosphate, meaning that it contains 3 phosphates.
ADP means adenine di-phosphate, which means it only has 2 phosphates.
ATP is usable energy, whereas ADP is not able to be used until it adds another phosphate group and becomes ATP.
