Which of the following ecological factors causes food shortage?
Answer Details
Drought is the ecological factor that causes food shortage. Drought is a prolonged period of abnormally low rainfall or lack of moisture that leads to a shortage of water for crops and livestock. This lack of water leads to poor crop yields and can even cause crop failure, leading to food shortages. In areas where agriculture is the main source of livelihood, drought can have devastating effects on the local economy and can lead to famine and malnutrition.
