Answer:
C- Species richness will be related to actual evapotranspiration.
Explanation:
Evapotranspiration is typically known to be directly proportional to specie richness in both plants and animals.
Why? Evapotranspiration provides ample temperature and humidity through its mode of operation. Typically, evapotranspiration would require water, which is gotten from rainfall. However, these same rainfall is aided through evapotranspiration. Aiding this cycle, is what improves specie richness in any environment.
