Consider a wetland habitat. Imagine a very hot summer with little rain. What would be the density dependent limiting factor for the populations of all animals living here

The density dependent limiting factor for the population of all animals living there is the supply of water or watering holes that are available within the environment. Sometimes, animals decrease in their population when water resources are not available. Almost all living organisms on Earth are dependent on water and cannot survive without, rising temperatures can give way to such scarcity.
