Summary Introduction

To analyze:

Whether the rate of stomatal conduction has increased or decreased from the graph’s data.

Introduction:

The stomatal conductance is the amount of CO₂ entering and water evaporated over a time period from stomata. It is usually measured in mol m⁻² s⁻¹. The following graph summarizes the data obtained by researchers from specimens of preserved collections and stomatal conductance in leaves from oak trees and pine trees that grew at different time intervals under different CO₂ levels.
