For a sustainable site plants should be selected that minimize evapotranspiration. What is evapotranspiration?
A: The quantity of pesticide a plant requires
B: A plant ability to attract pests
C: The quantity of fertilization a plant requires
D: The loss of water from a plant leaves

参考答案: D

本题解释:
A plant with a high evapotranspiration rate will lose more water to the air than a plant with a lower evapotranspiration rate. What this means is the plant with the higher rate will require more watering, and thus the consumption of more natural resources. A cactus (low) vs. a perennial (high) is an example.
