Explanation:

A drought is a lack of water over an extended period. It directly reduces the availability of water and other related resources. Birth/death rate can be indirectly affected, immigration is more related to human - choice and habitat change not directly to drought, and available niche is more about species' ecological role. Resource supply, especially water resources, is directly impacted by drought.
