Crops respond initially to the stress caused by the drought, they will take in less carbon dioxide.
A plant that may be widely cultivated and harvested for food or profit is considered to be a crop. A crop is what is produced when many plants of the same sort are grown in one location. The majority of crops are grown in aquaculture or agriculture. Macroscopic fungi and marine macroalga are examples of crops. If a drought kills all of a farmer's crops, the farmer may lose money. A farmer may need to spend more money on irrigation or drill new wells if his or her water supply is too low. Ranchers might have to pay more money for livestock feed and water.
In crop production, a stressor is regarded as anything that lowers output, whereas a growth promoter is regarded as something that raises yield. Grant-making and governmental organizations formally see many inputs that increase crop productivity as unrelated to stress.
