The answer is the first one
Answer:
High stomatal conductance
Explanation:
Plants with a high photosynthetic capacity have a high stomatal conductance, in the absence of environmental stress (Reich et al., 1999, 1997). This enables plants with a high photosynthetic capacity to gain carbon rapidly, at the cost of high rates of water loss.
A verticle group (up and down) is called a GROUP. The horizontal groups (left to right) are called PERIODS
