Explanation:
Detailed explanation-1: -Effects of elevated CO2 on insect pests. In general, host plants grown under elevated CO2 are less nutritious to insect herbivores, which can affect their behaviour and performance. Phenotypic host-plant changes typically make leaf material eaten by insects less nutritious.
Detailed explanation-2: -Thus, plants should generally be grown at warm temperatures of 70°F to 75°F to avoid excessively long production times. By growing cold-sensitive crops at warm temperatures, you can actually reduce the amount of energy used for heating-on a per-crop basis-than if they were grown at cooler temperatures.
